I came across one of those depressing Population losses continue across WNY, according to Census estimates stories in the Buffalo News
"Erie County lost 5,001 residents last year, continuing a decade-long trend of annual population losses seen here and across upstate New York, according to new population estimates from the U.S. Census Bureau."
What was interesting in the story, though, was a link to Population Change in all U.S. Counties: A searchable database. The details of the population growth or decline shows births and deaths for the past seven years. Of course, it's a variation of The Population Estimates from the Census Bureau, released on March 20, 2008, but it's still rather nifty.
