census data
American Community Survey

Geographical Mobility/Migration refers to the movement of people within the United States from one location to another at various geographic levels. People who moved from abroad are also included

The American Community Survey (ACS) and the Puerto Rico Community Survey (PRCS) ask respondents age 1 year and over whether they lived in the same residence 1 year ago. For people who lived in a different residence, the location of their previous residence is collected. ACS uses a series of monthly samples to produce estimates. These samples are based ACS surveys gathered over either one year, three years, or 5 years.

State to state migration flows are available annually based on the ACS 1 year samples starting with 2005, based on the 3 year samples starting with 2005-2007, and based on 5 year samples starting with 2005-2009.

County to county migration flows are based on 5 years samples starting with 2005-2009.

In addition to the county-to-county flow files, there are similar files that substitute minor civil divisions (mcd), in place of counties, for states where they serve as general-purpose local governments. These states are Connecticut, Maine, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, and Wisconsin.

The national County-to-County Migration Flows file reports both inflow and outflow of persons between counties and, for both counties, reports:
the total population one year and older,
total nonmovers,
total movers within the U.S.,
within the same county,
total movers from a different county with the same,
total movers from a different state, and
total movers from abroad (includes foreign countries, PR, and U.S. Island Areas).

The data files specific to New York State were based on extracts from the national County-to-County Migration Flows file.

Note: people living in group quarters (e.g. adult correctional facilities, nursing facilities, college/university student housing, and military quarters) were added to the sample for the first time starting with the 2006 ACS
