Final answer:
The United States Census Bureau and the Internal Revenue Service are reliable sources for data on migration and population change per state.
Step-by-step explanation:
A reliable source for data about migration and population change per state is the United States Census Bureau. The Census Bureau conducts regular surveys and collects data on various demographic factors, including migration and population change, at the state level.
One example of a specific Census Bureau source is the American Community Survey (ACS). The ACS provides detailed information on population and housing characteristics, including migration patterns, for every state in the United States.
Another potential source is the Internal Revenue Service (IRS). The IRS collects data on the migration of individuals and households for tax purposes. This data can provide insights into the patterns of population change in different states.
