Using Census Flows Mapper, you can see how migration in and out of your county compares with other counties around the country. Today’s release of statistics from the 2008-2012 American Community Survey looks at employment-themed characteristics, such as employment status, work status and occupation, of people who moved to a different county one year ago (or within the last year).
The movement of people from origin to destination is often referred to as a flow. There are three types of flows: inflows (people who move into an area), outflows (people who move out of an area) and net flows (the resulting calculation of inflows minus outflows). Los Angeles County to Orange County, Calif., is among the largest flows in Census Flows Mapper, which allows users to see the county-to-county relationships for inflow, outflow and net migration.
Take a look at these maps and see how they tell the story of the movement in and out of Los Angeles County.
The map above shows inflows, or people who move into an area. From the inflow map, we can see that there is a strong relationship between Los Angeles and its surrounding counties In other words, people from nearby counties move to Los Angeles. Additionally, Los Angeles draws population from counties throughout the West Coast.
From the outflow map, we again can see that there is a strong relationship between Los Angeles County and its surrounding counties, such as San Bernardino, Riverside and Orange. In other words, people from Los Angeles County also move to surrounding counties. However, we can also see that there is some outflow to counties in the Northeast corridor.
Net migration flows look at both those coming to and leaving a county. They are either positive (inflow > outflow) or negative (outflow > inflow) and denote the direction of the flow. For example, Los Angeles County loses population to Riverside County in the net flow; Los Angeles County gains some population from Cook County, Ill. (Chicago).
Try Census Flows Mapper and see what the maps of migration look like for your area. You can also see different characteristics in previous year’s versions. Those versions included sex, age, race and Hispanic origin (2006-2010), and educational attainment, household income and personal income (2007-2011).
