African-Born Population in U.S. Roughly Doubled Every Decade Since 1970

      The foreign-born population from Africa has grown rapidly in the United States during the last 40 years, increasing from about 80,000 in 1970 to about 1.6 million in the period from 2008 to 2012, according to a U.S. Census Bureau brief released this week. The population has roughly doubled each decade since 1970, with the largest increase happening from 2000 to 2008-2012.

      The Foreign-Born Population from Africa: 2008-2012, a brief based on American Community Survey statistics, shows that the African foreign-born population accounts for 4 percent of the total U.S. foreign-born population. No African country makes up the majority of these immigrants, but four countries — Nigeria, Ethiopia, Egypt and Ghana — make up 41 percent of the African-born total.

      “The brief — the Census Bureau’s first focusing on the African foreign-born population — highlights the size, growth, geographic distribution and educational attainment of this group,” said Christine Gambino of the Census Bureau’s Foreign-Born Population Branch, who is one of the brief’s authors. “We have found that the African-born population tends to be more educated and accounts for a relatively large proportion of the foreign-born population in some nontraditional immigrant gateway states such as Minnesota and the Dakotas.”

The true true size of Africa

LAST month Kai Krause, a computer-graphics guru, caused a stir with a map entitled "The True Size of Africa", which showed the outlines of other countries crammed into the outline of the African continent. His aim was to make "a small contribution in the fight against rampant Immappancy"—in particular, the fact that most people do not realise how much the ubiquitous Mercator projection distorts the relative sizes of countries.

A sphere cannot be represented on a flat plane without distortion, which means all map projections distort in one way or another. Some projections show areas accurately but distort distances or scales, for example; others preserve the shapes of countries but misrepresent their areas.
