For Census 2010 Data and Mapping - Please Click Here.
The 2007 Hamilton County Demographic Atlas is a document that maps data prior to the Census 2010 Release including data from the Ohio Department of Education, FBI and other data sources. The goal is to provide a picture of settlement patterns and concentrations of different demographic variables. To name just a few examples, this report answers and displays, "Where are the highest concentrations of poverty in Hamilton County?", "Where are the schools that achieved the highest rating from the Ohio Department of Education?" and "What areas in the county have the lowest crime rates?". County officials, decision makers, citizens and potential business owner start ups can all utilize these maps to gain a picture of areas that most interest them.
Both Summary File 1 and Summary File 3 data sets were used in this report from the US Census. A few maps compare change between the 1990 and 2000 Census and 1998 and 2002 County Business Patterns. The majority of the maps are thematic maps (polygons with colors representing different percentages of the variable that is mapped) with a few point theme maps (dots are symbols that represent a variable). Several Appendices Maps provide the reader with major street layers and jurisdictional boundaries. These can be used in conjunction with the thematic maps help the readers get their bearings. The most common level of geography used is the Census Block Group. Each map contains a detailed description of what is being mapped. Many of the maps utilize the same legend so they can be compared directly with each other. The majority of the maps provide the County average so the reader can view areas that are above and below the County average.
It is not the goal of this report to provide 'exact' numbers. However, the Appendix Maps can be used in conjunction with the thematic maps to provide a population estimate for the area being viewed. Specifically, if the viewer is looking at a block group and sees that between 20-30% of the total population is Hispanic or Latino, but the viewer wants to know exactly how many Hispanic or Latinos live in that Block Group, Appendix C can be used to determine the total population within that Block Group. Simple math (total population multiplied by .25) can be used to get a rough estimate of how many Hispanic or Latinos reside in that Block Group. Each map indicates within the text portion which Appendix Map can be used in conjunction to estimate the total population.
NEW 7/2005 - Several new maps have been added to the site including the Regional change in population from 2000 to 2004 and the Regional change in jobs from 1998 to 2002.
