2010 Census Day - APRIL 1st Short Form Population count Age, Race, Sex, Owner/Renter


4 What is your Local Response Rate?

5 Urban Boundaries Census Defined Urban Area (UA)
Adjusted Urbanized Area (UZA) Metropolitan Planning Area (MPA) Non-Attainment Area

6 Boundaries - the Important thing
Census Defined Urban Area (UA) - Population + $$$ Adjusted Urbanized Area (UZA) - Functional Class Metropolitan Planning Area (MPA) - MPO Jurisdiction Non-Attainment Area The Letters UZA and UA often get mixed up

7 Boundaries - some names people use
Census Defined Urban Area (UA) Census Urbanized Area (UZA) Adjusted Urbanized Area (UZA) Federal Aid Urban Area (FAUA) FHWA Adjusted Boundary Adjusted Urban(ized) Area Metropolitan Planning Area (MPA) Planning Area MPO Boundary

8 What’s an MPO? 100K - Threshold Grandfathering
NARC - Status Quo AASHTO -Somewhat Vague FHWA - Internal House - T+I Committee, HR ____ Senate - 100K - Threshold Grandfathering 200K - Project Selection Authority 1 Million+ Special Funding and Requirements

9 Census Defined Urban Area (UA)
2000 density based, automated process, identified urban clusters (2,500 pop), ignored place boundaries and built from Census Blocks 2010 Census Bureau still deciding process Investigating use of place of work data via ACS, reviewing land use covers and digital elevation maps and satellite imagery, thinking about using household densities and building from Census Tracts. Look for criteria for defining urbanized areas and clusters in Spring 2010 in Federal Register feb. 2009

Standard Tabs ACS Sample PUMS Records PUMAs are the zones used from PUMS data

14 NE Illinois (2008 pop estimate)
Why are PUMAs Important? NE Illinois (2008 pop estimate) Chicago Let’s Look at Annual Data Annual Data 65K+ Note the areas in gray We call this Swiss Cheese

15 Why are PUMAs Important?
NE Illinois (PUMAs) Tabulation Area for ACS Represent 100K Complete Coverage Smaller than Counties NO Swiss Cheese

16 Why are PUMAs Important?
How many PUMAs should this area have? City of Chicago 2000 PUMAs Why are PUMAs Important? - Defines areas for analysis - Tabulation Area for ACS Who Defines Them? - The Community - Led by State Data Center When are They Defined? - Summer 2011 - Criteria out Spring 2010 2,896,016 (2000 Pop)
