IMPORTANT NOTE: The estimates in tables 1 through 3 were prepared by the U.S. Census Bureau using a simplified methodology that assumes uniform growth of household population within counties and generally holds group quarter population constant. Unlike prior subcounty estimates, these figures do not reflect local data on housing stock or group quarter population. Because these estimates are not based on subcounty statistics, the reported variations within counties are not necessarily meaningful.
Thus, the estimates in tables 1 through 3 are not suitable for identifying local patterns of change within counties. The alternative estimates from SEMCOG at the bottom of this page provide a better picture of local population change in the seven counties of Southeast Michigan.

Table 1:
Estimated Population of Cities, Villages, and Townships or Remainders of Townships: 2010-2011 (xls)
(cities, villages, and townships sorted by county; cities that cross county lines and villages that cross township lines are broken into separate parts, and population for townships containing villages is reported separately or the villages and for the remainder of the township)
Table 2:
Estimated Population of Incorporated Places: 2010-2011 (xls)
(cities and villages, sorted alphabetically)
Table 3:
Estimated Population of Minor Civil Divisions by County: 2010-2011 (xls)
(cities and townships, sorted by county; cities that cross county lines are broken into separate parts)
Methodology

Census Bureau staff have provided the following statements regarding the temporary simplifications of the methodology for 2011:
"This year's population estimates will tend not to show differential growth for cities and towns within a county due to a temporary change in the method used to estimate housing units. As a result of this method change, areas within a county are likely to grow at the same rate."
"Our method of producing housing unit estimates is different this year than in years past. The Vintage 2011 housing unit estimates" [which are the basis for allocating county population totals to subcounty units] "do not rely on the usual components of housing change (building permits, non-permitted builds, mobile home shipments, and housing loss), which we used last decade to produce the housing unit estimates. Instead, we created the Vintage 2011 estimates by extrapolating the average monthly change in housing units at the county level, then summing these estimates to create estimates for the states and nation. To produce subcounty housing unit estimates, we distributed the extrapolated county estimates down to each subcounty area within a county based on 2010 Census proportions."
"We chose not to use the components of change model for 2011 since we are presently evaluating the 2010 housing estimates relative to the 2010 Census results, and considering improvements to the existing housing unit method for the new decade. We expect to return to the components of change model for the 2012 estimates."
