Census Data of the City of Chicago, 1930, and Census Data for the City of Chicago, 1934 have accurate titles. Records can perhaps be found most easily by doing "Anywhere keyword" searches on such terms as "Chicago," "maps," and "census."

Census data are also available for zip codes, congressional districts, and (outside of Chicago proper) places (e.g., cities), and minor civil divisions (i.e., townships). All the variables enumerated at the tract level are, in theory, enumerated at the block group level too, but data suppression is more common, and census-to-census comparison is difficult. Block groups consist of several blocks there are typically between three and five block groups to a tract. There are something like 10,000 census blocks in Chicago.Ĭensus data are available for other geographic units as well. Census-to-census comparison is difficult because of changing systems of block identification. Only limited data are available at the block level, and some figures that one might think would be available are suppressed to prevent identification of individuals. Census blocks correspond closely to blocks that any urban resident would identify. Census tracts in the suburbs have changed a great deal over the years, in most cases by splitting.Ĭensus blocks. Census tracts in the city of Chicago have remained nearly constant since the 1920s, but the numbering system has changed. Census tracts ideally have something like 1200 households (perhaps 2000-4000 people), but, in Chicago, population varies from 0 up to 10,000. Census tracts are small areas that are supposed to be somewhat homogeneous.
Although most community area boundaries are coincident with census tract boundaries, because the city limits intersect census tract boundaries in several places, it is not possible to derive community area data from census tract data in a straightforward way.Ĭensus tracts. Census Bureau does not compile data for community areas. They have the virtue of consistency except for the addition of O'Hare and the splitting of Edgewater from Uptown, they have remained unchanged since their inception. They have been used ever since by the city government as statistical units. They were apparently first proposed by members of the Social Science Research Committee at the University of Chicago during the 1920s. Many, but not all, do in fact correspond quite closely to neighborhoods that would be recognized by their residents examples of these are Hyde Park and Uptown. Community areas, of which there are 77 in Chicago, are supposed to be homogeneous neighborhood-like districts.
