In December of 2010 the first release of the 2010 Census included state level population data that can be viewed on an interactive map. Additional information including age, sex, race, households and housing tenure will be released for virtually every geographic level possible down to the smallest Census block level in the Spring of 2011. While the 2000 Decennial Census provided information such as income, poverty, journey to work, education, and employment data, these detailed characteristics are no longer reported by the Decennial Census and are instead available from the Census Bureau's American Community Survey.
MRCOG hosts a wide array of Census data available for viewing and downloading. The 2000 Decennial Census includes two types of data: 100-percent count and sample. 1. The 100-percent count, or "short-form" data, includes the results from questions that were asked of all census respondents. The data pertain to population and households. 2. Sample data, or "long-form" data, was collected from approximately one in every six households. There was some variation in the sampling: in rural areas the sample was one in every two households while in the densest urban areas the sample was one in every eight households. The data are much more detailed than the 100-percent count, and pertain to a wide array of demographic, housing, social, and economic variables.
The American Community Survey is an ongoing survey that produces detailed data releases on a regular basis. It replaces the Decennial Census "long form" in an effort to provide communities with more timely data on how they are changing, thereby equipping them with the information they need to best respond to these changes. Because ACS results are derived from relatively small sample sizes, we recommend that the data be viewed as percentages and that analysis focuses on relative comparisons rather than actual numbers. For actual population and housing totals, we recommend using the Population Estimates shown above, or waiting for the 2010 Census data to become available in early 2011.
The Census Transportation Planning Package (CTPP) offers a set of special tabulations from the US Census Bureau pertaining to commuting characteristics by place of residence, place of work, and home to work flows. It is a cooperative effort sponsored by the State Departments of Transportation under a pooled funding arrangement with the American Association of State Highway and Transportation Officials (AASHTO). As the largest and most up-to-date survey of transportation data available for the region, the CTPP is a valuable dataset for transportation planners.
A variety of commuting characteristics and transportation profiles are available from MRCOG.
The Census Bureau annually produces population estimates by county using a component of change method; summing births, deaths, and migration. Municipal estimates are produces using a housing unit method that is controlled to the county population. In addition, MRCOG produces an alternative set of population estimates based on local data we collect including housing permits, school enrollment, and utility hook ups.
