RE: [CTPP] 2000 vs 2010 Municipal Boundaries

April.. The 2010 Redistricting data as released by the Census Bureau is based on the January 1, 2010 governmental unit boundaries as reported in the 2010 Boundary and Annexation Survey. What USA Today is saying is that the comparison for Place A does NOT take into account any boundary changes (ie: the 2000 data is based on January 1, 2000 boundary and the 2010 data is based on the January1, 2010 boundary). If there is a new incorporation for 2010 (ie: the place did not exist in 2000), then they do not provide a comparison.

My confusion is partly due to the USAtoday.com census tool. If you look up localities/municipalities on USAtoday.com and at the bottom is a hot link "about this data." In this pop-up, it says the following about population..... Comparisons between 2000 and 2010: For states, counties and localities, boundary changes were not considered. If a city annexed land, for instance, the comparison matches the population in the 2000 boundary with the population in the 2010 boundary. No comparison is made for areas that are substantially new or the product of a merger or consolidation. I understood this to be saying that the 2000 vs. 2010 percent comparison and the 2010 population count is based on the 2000 US Census locality/municipality boundary. Now I am exploring AF2 and I want to ensure I understand what boundary, 2000 or 2010, the population count refers to before doing additional analysis. Can anyone confirm that the Redistricting data just released for 2010 population counts for municipalities/localities is based on 2000 or 2010 municipal/local boundaries? Because of annexations and other issues/changes some boundary changes are now different in multiple municipalities in Montgomery MPO. Thank you for your help.
