Who is left in the city...

So I am just looking at some recent census data from the 2005 American Community Survey that has been coming out over the last month. Here is a factoid of note. The household population (which excludes those living in institutions, college dormitories, and other group quarters) of the city of Pittsburgh in 2005: 274,140 (I seem to have made that number up.. correct number is 284,366)... thats it. and of that number 32K are enrolled in college or graduate school. I am a little curious how many of remaining city residents have some tie to the colleges and universities located in the city.

What was the household population in 2000?

I wonder if the universities have just the number of employees back 5 years ago, and now. At least from the growth of new buildings, CMU must have hired a bunch of people at least in the last decade.

Maybe I am looking in the wrong place.
But for the ACS PIT 2005, I find a total pop of 284,366, and for 2000 (tab next to 2005), I find 334,563. This may be mixing apples, and oranges.

I went to American Community Survey, and then the Quick Start, typed in "pittsburgh" into the city name text box.

Here is another city pop est for 2000 and 2005. For PIT, the number are 316,718 (2005), and 334,563 (2000).

316,718 (2005) and 334,563 (2000)

An estimated 5.35 percent population loss in five years. Ouch.

the 334K number is everyone.. the lower number in the ACS is household population, which because it excludes group quarters is prety much apples and oranges for a city like Pittsburgh with both concentrated dorms, jails etc. but I wasnt really commenting about the trend (thus the lack of context in that regards Mark).. but more just about how to think about the city's population in general. People know the students are here, but I am not sure people realize how big a factor they are in the city these days.

So is Pitt something like 75% to 80% of that 32K?

How come I can't find that 274,140 number online for PIT? Is there another adjustment missing?

Of that 5% city (not MSA) drop, just the latest year estimate was a drop of 1.3% from 320,828 (2004) to 316,718 (2005). I remember a simliar 1%+ drop between 2003 and 2004. For 2000 to 2005, that puts us at #251 out of 254 cities. Only the cities of New Orleans (-6.2%), Detroit (-6.8), and Cincinnati (-6.8%) lost a greater percentage. Oh, we tied with CLE with the -5.3% lost.

you know.. I now pull up 284,366 via the interactive ACS site.. did I imagine that 274K number up? I will annotate the error in the post. I'd say I mistyped but I got the last 3 digits different. alas.

Could have been a glich on the census site.

To combine the two factoids, over the five years, the loss of total city population is like 56% (17,845) of the 32K students left.
