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:
- Population, race, age, housing, commuting, income data from the 2000 U.S. Census. 2005 Population estimates are also from the U.S. Census.
- Crime data from the U.S. Federal Bureau of Investigation. Most of the data is from 2003 but some data is from 2000-2002.
- Climate data from the National Oceanic & Atmospheric Administration.
- Historic photographs are from the Library of Congress, Prints and Photographs Division, Detroit Publishing Company Collection.
- Political contribution data from donations in 2003-2004 for national elections only from the Federal Election Commission.
- High school data from the National Center for Education Statistics for the 2003-2004 school year.
- Job data (found on the "Work" pages) from the Bureau of Labor Statistics, 2006.
- Landmark information from the National Register of Historic Places.
- College and university data from the U.S. Department of Education, 2005.
Where appropriate, comparative 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.
