Data Sources & Definitions
The information on CityTownInfo.com (CTI) is derived from our own research, contributions by site users, and a variety of government and public domain sources. Government and public domain sources include:
- College and university data from the U.S. Department of Education, primarily reflecting the 2007/08 school year.
- Jobs, salaries and industry data from the Bureau of Labor Statistics, 2008. Job growth predictions from 2006.
- Population, race, age, housing, commuting, income data from the 2000 U.S. Census, the last year in which a census for the entire country was conducted. 2005 Population estimates are also from the U.S. Census.
- Crime data from the U.S. Federal Bureau of Investigation. The data is mostly from 2003.
- Climate data from the National Oceanic & Atmospheric Administration.
- Historic photographs from the Library of Congress, Prints and Photographs Division, Detroit Publishing Company Collection.
- Political contribution data from the Federal Election Commission.
- Landmark information from the National Register of Historic Places.
Where appropriate, comparative city and town data is normalized by examining per capita statistics rather than absolute numbers.
"Peers" (similar sized places nationwide) are classified into 4 partitions:
- Places with a population over 125,000 people
- Places with a population between 25,000 and 125,000 people
- Places with a population between 5,000 and 25,000 people
- Places with a population less than 5,000 people
For example, a city with a population of 35,000 has in its peer group all cities and towns in the United States with a population of between 25,000 and 125,000 people. All national comparisons are made to places in with this population profile. However, state comparisons are made against all places within the state, regardless of population size.
