State Personal Income and Per Capita Income 2005-2010

After declining last year for the first time since 1949, U.S. personal income rose three percent in 2010 to more than $12.5 trillion, according to a release from the Bureau of Economic Analysis (BEA). U.S. per capital personal income, which had also dipped in 2009, rose 14.6 percent to $40,584 last year. Both U.S. total and per capita personal income, however, remained below their peak levels in 2008. The largest percentage increases in personal income came in the Southwest region (Arizona, New Mexico, Oklahoma and Texas) and the Mideast region (Delaware, District of Columbia, Maryland, New Jersey, New York and Pennsylvania.

Increase in household size could slow economic recovery

From USA Today:

The number of people living under one roof is growing for the first time in more than a century, a fallout of the recession that could reduce demand for housing and slow the recovery.

The Census Bureau had projected the average household size would continue to fall to 2.53 this year. Instead, the average is likely to hit 2.63, a small but significant increase because it is a turnabout.

The 10 most segregated urban areas in America

From Salon.com:

Decades after the end of Jim Crow, and three years after the election of America's first black president, the United States remains a profoundly segregated country.

That reality has been reinforced by the release of Census Bureau data last week that shows black and white Americans still tend to live in their own neighborhoods, often far apart from each other.

How the districts may shift

The CUNY Mapping Service has mapped the 2010 population counts by legislative district in New York, to gauge how the districts (state and Congress) may need to shift within and across regions. This does not yet account for the other issues that will play a central role in redistricting – compliance with federal statutes and court decisions, prison population counts for state & local districts, etc – but it’s an interesting first-cut analysis of what’s to come.

2010 Center of Population


The U.S. mean center of population, as of April 1, 2010, is near Plato, Mo., an incorporated village in Texas County. The U.S. Census Bureau calculated this point as the place where an imaginary, flat, weightless and rigid map of the United States would balance perfectly if all 308,745,538 residents counted in the 2010 Census were of identical weight.

Ever since Chestertown, Md., was determined to be the center of population after the first census was conducted in 1790, the center of population has told the story of America, illustrating how we've grown as a nation. It follows a trail across the country ─ across Maryland, Virginia, West Virginia, Ohio, Kentucky, Indiana and Missouri ─ that reflects our history of settling the frontier, manifest destiny, waves of immigration and regional migration.

The Census Bureau will install a commemorative "geodetic control mark" at a site near the official coordinates during a dedication ceremony in April 2011. This survey disc will be used by satellites and land surveyors to conduct scientific surveys to generate precise position data that serve as the foundation for accurate mapping and charting in America.

State Government Tax Collections Decrease $14 Billion in 2010

Census Bureau Reports State Government Tax Collections Decrease $14 Billion in 2010; Income Tax Revenue Down 4 Percent, Corporate Tax Revenue Down 7 Percent

State government tax collections decreased $14.3 billion to $704.6 billion in fiscal year 2010, the U.S. Census Bureau reported today. There was a $65.8 billion decrease in 2009.

These new data come from the 2010 Annual Survey of State Government Tax Collections, which contains annual statistics on the fiscal year tax collections of all 50 state governments, including receipts from licenses and compulsory fees. Tax revenues also include related penalty and interest receipts of the governments.

“The first response of researchers and analysts, when confronted with a new tax policy question, is to see what the Annual Survey of State Government Tax Collections data tell them about the question,” said John Mikesell, a Chancellor’s Professor at Indiana University’s School of Public and Environmental Affairs. “These data make the public finance world easier to understand and to analyze.”

According to the survey, corporate net income tax revenue was $38.2 billion, down
6.6 percent, while tax revenue on individual income was $236.4 billion, down 4.4 percent. General sales tax revenue was $224.5 billion, down 1.8 percent. These taxes comprised 70.8 percent of all state government tax collections nationally.

This survey provides an annual summary of taxes collected by state for up to 25 tax categories. Eleven states saw increases in total tax revenue in fiscal year 2010, led by North Dakota (9.6 percent), North Carolina (4.8 percent), Nevada (4.0 percent), and California (3.8 percent). The states with the largest total tax revenue decreases were Wyoming (23.4 percent), Louisiana (14.2 percent), Oklahoma (13.5 percent), and Montana (11.0 percent). States with the largest percent decrease in revenue from individual income taxes were Louisiana (22.2 percent), Tennessee (22.2 percent), North Dakota (18.0 percent) and New Hampshire (16.2 percent).

Severance taxes — collected for removal or harvesting of natural resources (e.g., oil, gas, coal, timber, fish, etc.) — were down $2.3 billion, a 17.4 percent decrease. This followed a 24.8 percent decrease in fiscal year 2009. The largest decreases in severance tax revenue were seen in the West and South. The Midwest saw an increase in severance tax revenue this year.

Revenue on taxes imposed distinctively on insurance companies and measured by gross or adjusted gross premiums (insurance premium sales tax) increased $754.0 million, up
5.0 percent. This followed a 4.6 percent decrease in fiscal year 2009. The largest increases in insurance premium sales tax revenue were seen in the Northeast and South.

These data do not include employer and employee assessments for retirement and social insurance purposes. Also excluded are collections for the unemployment compensation taxes imposed by each of the state governments. In addition, these data include tax collections for state governments only; they do not include tax collections from local governments.

Although the data are not subject to sampling error, the statistics are subject to possible inaccuracies in classification, response and processing. Every effort is made to keep such errors to a minimum through care in examining, editing and tabulating the data.

The tax revenue data pertain to state fiscal years that ended June 30, 2010, in all but four states. Amounts shown for these four states reflect the different timing of their respective fiscal years, which were the 12-month periods ending on March 31, 2010, for New York; Aug. 31, 2010, for Texas; and Sept. 30, 2010, for Alabama and Michigan.

The World's Women and Girls 2011 Data Sheet


Source: Population Reference Bureau

In developing countries, 35 percent of women ages 20 to 24 report having been married by age 18. And, in the poorest regions of the world, according to The World's Women and Girls 2011 Data Sheet, the proportion is even higher, with levels ranging from 45 percent in South Central Asia to nearly 40 percent in sub-Saharan Africa. Nine countries have prevalence rates above 50 percent.

Despite legal means, early marriage (before the age of 18) persists, along with the associated risks of adolescent childbearing. Early marriage can also curtail the opportunities girls may have for education. In countries and regions with the highest proportions of early marriage, girls' educational attainment is adversely affected. Literacy rates, primary school completion, and secondary school enrollment are all lower than that of boys.

State of the News Media 2010

From Pew Research:

The future of news ultimately rests on...long-term concerns: What are the prospects for alternative journalism organizations that are forming around the country? Will traditional media adapt and innovate amid continuing pressures to thin their ranks?

And with growing evidence that conventional advertising online will never sustain the industry, what progress is being made to find new revenue for financing the gathering and reporting of news?

Census Bureau Survey Shows Poverty is Primarily a Temporary Condition

Poverty is not necessarily a permanent condition, according to a report released this week by the U.S. Census Bureau. While 29 percent of the nation’s population was in poverty for at least two months between the start of 2004 and the end of 2006, only 3 percent were poor during the entire period.

The report, Dynamics of Economic Well-Being: Poverty, 2004-2006, traces a sample of U.S. residents over the aforementioned 36-month period and examines how many of them were poor during at least some portion of that time and how long their poverty spells lasted. It also looks at how many fell into poverty, how many climbed out of it and how many stayed poor during the period. The data are presented by various demographic and socioeconomic characteristics.

The data were collected by the Survey of Income and Program Participation (SIPP) between February 2004 and May 2007 from a representative sample of U.S. households who were interviewed every four months during the period. These estimates should not be confused with the official poverty estimates, which are based on the Current Population Survey (CPS) Annual Social and Economic Supplement. The CPS captures a snapshot of well-being at a single point in time. See HERE. Limited data from more recent SIPP interviews are available. Tables on the Census Bureau website and in the appendix of the report provide some estimates for 2007 and 2009.

According to the report, poverty can be a persistent condition: among the 33 million people who were poor at the start of the period — January and February 2004 — 23 percent remained poor throughout the next 34 months.

However, many people did escape poverty: 12 million, or 42 percent, who were poor in the 2004 calendar year were not in poverty in 2006.

As some moved out of poverty, others moved into it. About 10 million who were not in poverty (4 percent) in 2004 slipped into poverty by 2006.

Other highlights include:

-- For those who were in poverty for two or more consecutive months from 2004 to 2006, the median length of a poverty spell was 4.5 months. Almost half of such spells ended within four months while about 12 percent lasted more than 24 months.

-- More than half of those who did exit poverty continued to have income that was not significantly above the poverty level (less than 150 percent of the poverty threshold).

-- Children younger than 18 tended to stay poor longer than working-age adults (ages 18-64): the median length of their poverty spells was 5.2 months, while for those 18 to 64, the median was 4.2 months. Older adults (65 and older) had the longest stays in poverty of any age group: a median spell of 6.7 months.

-- People in female-led families had longer median poverty spells than those in married-couple families.

St. Patrick’s Day

Irish-American Heritage Month (March) and St. Patrick’s Day (March 17): 2011

Originally a religious holiday to honor St. Patrick, who introduced Christianity to Ireland in the fifth century, St. Patrick's Day has evolved into a celebration for all things Irish. The world's first St. Patrick's Day parade occurred on March 17, 1762, in New York City, featuring Irish soldiers serving in the English military. This parade became an annual event, with President Truman attending in 1948. Congress proclaimed March as Irish-American Heritage Month in 1995, and the President issues a proclamation commemorating the occasion each year.

2011 Alzheimer's Disease Facts and Figures

The Alzheimer’s Association Facts and Figures report (PDF) details the growing prevalence and escalating impact of Alzheimer’s and dementia on individuals, caregivers, families, government and the nation’s healthcare system.

Unpaid caregivers and stress
There are nearly 15 million Alzheimer’s and dementia caregivers providing 17 billion hours of unpaid care valued at $202 billion. Facts and Figures finds that caregivers not only suffer emotionally but also physically. Because of the toll of caregiving on their own health, Alzheimer’s and dementia caregivers had $7.9 billion in additional health care costs in 2010. More than 60 percent of family caregivers report high levels of stress because of the prolonged duration of caregiving and 33 percent report symptoms of depression.


Deaths from Alzheimer's disease
Alzheimer’s is the sixth-leading cause of death in the country and the only cause of death among the top 10 in the United States that cannot be prevented, cured or even slowed. Based on mortality data from 2000-2008, death rates have declined for most major diseases while deaths from Alzheimer’s disease have risen 66 percent during the same period.

No more Statistical Abstract?


A librarian posted this on the BUSLIB (Business Librarian) listserv this afternoon:

I couldn't take the uncertainty anymore so I called the Census Bureau and spoke to Ian O'Brien who's the Chief of the Statistical Compendia Branch. He said that the 2012 budget doesn't include funding for his branch, which would mean the elimination of not only the Statistical Abstract, but all titles produced by that branch (State and Metropolitan Area Data Book, County and City Data Book, etc.). No new editions would be produced in print or online.

I asked if there was any hope of changing this and he said that there's always a chance that Congress could be convinced to continue funding for the program. He said those who would like to save the Statistical Compendia Branch could write to their Senators and Representatives. I'm guessing this would go for the Federal Financial
Statistics Program as well.

So, start writing your letters and encourage others to do the same.

Analysis of County Boundary Differences Between 2000 and 2010 Census Geographies

by Joe Francis, Cornell Program on Applied Demographics

Background

Without doubt, data from the 2010 Decennial Census will show changes in the size, composition and distribution of the population in New York State compared to those same indicators from the 2000 Census. These changes will occur at all levels—county, towns, cities and places, tracts, block groups and blocks. In addition to changes in counts of population and housing units, as well as age, sex and racial groupings, there will be changes to the geographies associated with those levels.


While it is common practice to examine the population and housing changes amongst the administrative units under our respective purviews, we are less familiar with examining the changes in the spatial extent and composition of those same administrative units and component geographies (i.e. tracts, block groups, blocks). Consequently, census geographies have been of less concern. Yet we all know that changes in counts may be a function of both population dynamics and changes in redrawn boundaries that enlarge, shrink or reshape the county, town, city, and so forth. Failure to consider that geographies have changed means that when we compare population and housing changes across time, we are assuming that the spatial units have remained constant. Frequently this is an erroneous assumption which can lead to bad analysis and interpretation.

Purpose of Analysis

The purpose of this analysis of boundary differences is to examine the extent to which the changes we observe when comparing data from the 2000 Decennial Census to the 2010 Decennial could be a function of changes in geographies as well as a function of natural increase/decrease and net migration. By examining these boundary changes we establish a firmer basis for asserting that the changes (1) are due entirely to the demographic forces of natural increase/decrease and net migration or (2) are partly due entirely to boundary changes as well, or (3) are due to both.

There are two main reasons for raising the importance of boundary changes at this time. One is that these changes affect not only the Decennial Census but the American Community Survey data products as well. The second reason is that recent advances in GIS technology easily permit such an examination and thereby remove the anxiety of not knowing whether the assumption of common geographies from time one to time two to time three are constant.


True enough that boundary changes only immediately impact comparisons between decennial censuses, but in the not too distant future, that same issue will arise for the American Community Survey (ACS) data as well. As you know, the already reported ACS data are mainly based on 2000 census geography but within two years we face the additional complication of the ACS being tagged to the 2010 census geography (i.e. changes in geographies). Even now some ACS data are based on the 2010 geographies while other ACS data are not. (For additional details, see this Census page.)

Procedure

To increase our understanding of the size and structure of these boundary changes between 2000 and 2010 Census geography, the Cornell Program on Applied Demographics decided to examine the changes starting with changes in county boundaries. With the hope that this investigation will prove of some use to the Affiliates, we share our findings. This report is restricted to county boundary changes. A later report will be about sub-county boundary changes. All analyses were conducted using ArcGIS 10. Details of procedures used can be provided to interested users by writing to Joe Francis (jdf2@cornell.edu) .

Overall Results

Because county boundaries in New York have been relatively stable for over 70 years, we decided to begin the examination here, expecting few changes and a belief that this would be a good testing ground for working out a boundary examination and reporting procedure. To our surprise, there were 79 boundary changes detected in total at the county level. Not all 62 counties had a boundary change but several had more than one boundary difference involved. Montgomery County had the most with 11 differences. Fulton was next with 9. Orleans and Otsego each had 6. Sullivan had 5. Orange, Wyoming and Yates each had 4. Delaware and Schenectady both had 3. Albany, Chautauqua, Schuyler and Tompkins had 2. On the other hand, Allegany, Cattaraugus, Columbia, Hamilton, Herkimer, Oneida, Saratoga, Schoharie, Seneca and St. Lawrence each had 1 boundary change. Three of the observed changes involved counties along the Pennsylvania state line.


Upon examining these 2000-2010 discrepancies about half of them were long narrow slivers involving no housing units and were boundary adjustments we felt weren’t worth reporting. (If there is interest in these, we are happy to provide the details.) For this report, a decision was made to restrict our mapping and reporting to those differences involving at least an acre (4069 sq. meters) or more of land mass. This reduced the number to 42. Counties with 5 boundary differences of an acre or more included Fulton, Montgomery and Otsego. Delaware and Sullivan had 3, while Albany, Orleans and Wyoming had 2. Allegany, Cattaraugus, Hamilton, Herkimer, Oneida, Orange, Saratoga, Schenectady, Schoharie, St. Lawrence, Tioga, Washington, Wayne, and Yates had one each. Of course every boundary involves at least two counties, so more counties were involved than the above list indicates.


Not all of the 42 mapped boundary differences contain significant number of housing units (and therefore people), but a quick look at the jpeg files POSTED HERE will enable you to see what these boundary changes look like. Then you can decide whether or not the change is worth taking a closer look. Like any choice of a threshold cut-point, the choice of one acre or more was arbitrary but based on the idea that land area of that size could accommodate a significant housing worth looking into. In retrospect, we should have moved the threshold higher for the county boundary examination.

Next Steps

Because we are trying to document discrepancies that are of concern to you and report them to the Census Bureau, please let us know your concerns.


For our part at the Program on Applied Demographics, we plan to begin analysis of sub-county geographies next. We expect to see more and more significant changes at that level. Compared to counties, MCD are the next most stable administrative units. If analysis of MCS all works out, we will then move to tracts which involve more fluid dynamics.

Women in National Parliaments

The data in the table has been compiled by the Inter-Parliamentary Union on the basis of information provided by National Parliaments by 31 January 2011. 188 countries are classified by descending order of the percentage of women in the lower or single House.

In the United States of America, of the 435 members of the House of Representatives, 73 or 16.8%, are women, making it tied with Turkmenistan for 72nd place. Incidentally, 17 of the 100 U.S. Senators (17.0%) are female.

State of Sentencing 2010

Twenty-three states and the District of Columbia adopted new criminal justice policies—ranging from scaling back mandatory sentencing laws to reforming crack and powder cocaine sentencing disparities to improving parole supervision -- all aimed at reducing prison populations and facilitating successful reentry of ex-offenders, while at the same time, ensuring public safety.

Today, 7.2 million men and women are under correctional supervision. Of this total, five million are monitored in the community on probation or parole and 2.3 million are incarcerated in prisons or jails. As a result the nation maintains the highest rate of incarceration in the world at 743 per 100,000 population.

Breastfeeding works!


From Moms Rising:

A mountain of medical research demonstrates that breastfeeding improves the health of mothers and children. For this reason, the American Academy of Pediatrics recommends mothers breastfeed exclusively for six months. It also makes financial sense. A recent study in the medical journal Pediatrics estimates the country could save up to $13 billion per year in health care and other costs if 90 percent of U.S. babies were exclusively breastfed for six months.

Medical research shows that breastfeeding prevents children from developing life-threatening health conditions including SIDS, type 1 and 2 diabetes, asthma, childhood leukemia, and obesity.

The IRS [has decided] to make the cost of breast pumps and supplies tax deductible.
