Pittsburgh's Downtown Residential Population

Posted on Tuesday, November 08, 2011 at 11:47 am ET

For those asking about the population change in Downtown Pittsburgh that was referenced to us in the Pittsburgh Tribune Review today, here is what the data looks like.

It is not a straightforward exercise to show the change in Downtown's population. In 2000 the Decennial Census incorrectly located the population at the Allegheny County Jail at its former location along the 400 block of Ross Street which is located in Downtown Pittsburgh. In the 1990's, Allegheny County built a new jail located on 2nd Ave. which is located in a different census tract defined as part of the Uptown, or Bluff neighborhood. The result is that the populations the census records for census tracts making up both the Downtown and Uptown neighborhoods are incorrect. The location of the jail was correct in data enumerated as part of the 2010 decennial census.

To determine what is a good reference population to measure the changes that have taken place Downtown it is essential to not ignore the jail's population and its nominal change in location between the two census years.

Below is what the two decennial censuses (2000 and 2010) show for the total population and the group quarters populations in each year. Group quarters population can include both institutionalized and non-institutionalized. Most of the non-institutionalized group quarters population Downtown are residents of college dormitories or other college sponsored housing. The institutionalized group quarters population residing Downtown in 2000 was the incarcerated population at the jail.
