This blog is intended to go along with Population: An Introduction to Concepts and Issues, by John R. Weeks, published by Cengage Learning. The latest edition is the 12th (it came out in 2015), but this blog is meant to complement any edition of the book by showing the way in which demographic issues are regularly in the news.

Census Tract Level Data Now Available from American Community Survey

The US Census Bureau today released the first set of data from the American Community Survey that go down to the census tract level of geography. This was done by combining the respondents from the 2005 through the 2009 surveys. We are now getting very close to the promised equivalent to the long form on previous censuses, which has now been replaced by the ACS. Demographer William Frey at the Brookings Institution jumped quickly on this goldmine to evaluate levels of residential segregation by race in US metro areas.

America's neighborhoods took large strides toward racial integration in the last decade as blacks and whites chose to live near each other at the highest levels in a century.
Still, segregation in many parts of the U.S. persisted, with Hispanics in particular turning away from whites.
But, you don't need to take someone else's word for it. Check out the data yourself at
