About 130,000 People Moved Per DayWASHINGTON, March 19, 2013 /PRNewswire-USNewswire/ -- Across the country, 47.3 million people lived in a different house a year earlier and 17.3 million of them lived in a different county within the U.S., according to information the U.S. Census Bureau released today on migration. This translates to an average of about 130,000 people moving every day.

An estimated 44,020 people — or an average of about 121 per day — moved from Los Angeles County to San Bernardino County, Calif., which is the largest number of people moving from one county to another in the nation. The rest of the top 10 flows of movers were people moving among counties in the Miami, Phoenix, Detroit and Chicago metro areas. These findings were released in a series of County-to-County Migration Flow Tables, which come from data collected by the American Community Survey between 2006 and 2010. In the survey, household members were asked where they lived a year ago and responses were combined into a weighted average for the period. The tables give added information on current county of residence, the county of residence one year ago and the estimated number of movers between the counties. Additional tables provide the same information broken down by selected characteristics: age, sex, race or Hispanic origin. New Census Flows Mapper To help users understand and interact with these statistics, the Census Bureau has developed an online mapping tool called Census Flows Mapper. This application allows users to select a county in the U.S. and view the outbound, inbound and net migration flows for that county. Additionally, users can choose flows based on characteristics such as age, sex, race or Hispanic origin. The application also allows users to download data, zoom in and out on the map to an area of interest, view additional statistics of the selected county and save their map as a PDF file.
