Census Estimates
The population estimates visualized in this dashboard are courtesy of the United States Census Bureau. The U.S. Census Bureau is the leading source of statistical information about the nation’s people. Population statistics come from decennial censuses, which count the entire U.S. population every ten years, along with several other surveys. In addition to the decennial censuses, the United States Census Bureau produces and publishes estimates of the population for the nation, states, counties, state/county equivalents, and Puerto Rico. Estimates for the resident population for each year since the most recent decennial census are calculated using measures of population change including births, deaths, and migration.
More information about the specific methodology used to calculate census estimates can be found here:

Data Considerations
Data suppression criteria follows the criteria provided by the data source. Suppression criteria may vary across data sources and is used to maintain confidentiality.
Many data tabs include the option to view data as a count and as a rate. Count data is useful in looking at the total quantity of an event but may be influenced by the size of the underlying population. A rate means that the data was standardized to a common denominator and can be compared across geographic or demographic groups.
