Examining State-to-State Geographic Mobility

.. tools, resources and insights to examine U.S. by state migration 2011-2017 and migration flows in 2016 .. this post is an excerpt from the more detailed Web page http://proximityone.com/statemigration.htm.

In examining future demographic trends, the most challenging component of change to project (develop data values into the future) is migration. Migration, comprised net domestic and net international migration, is a function of many factors whose cause and effect behavior can change year by year, and geographic area by area. While this section is focused on states, the same scope of data is available to the county and sub-county levels. In this section, U.S. by state migration is examined using two data sources: annual population and components of change model-based estimates (2010-2017 model-based estimates) and annual American Community Survey estimates (ACS 2016 estimates). While these Census Bureau programs are highly related, the migration data/subject matter differ some.

The larger view shows a portion of a mini-profile for Florida. The mini-profile illustrates how these data are comprised … annual net domestic migration estimates and the sum over the years 2011-2017.

State OutMigration by Destination State
The model-based estimates, reviewed above, do not provide detail on state-to-state migration. Those data are provided by the related ACS 2016 estimates. Note that the ACS 2016 1-year estimates are for the calendar year 2016. From these data we can get the following migration detail … In 2016, there were an estimated 605,018 people who moved from a residence 1 year earlier, in a different state, to Florida. Florida experienced the largest number of movers (inflows) from other states among all states. 60,472 of these movers were from New York. See the interactive table in this section to examine similar characteristics for any state. These data are based on the 2016 ACS 1 year estimates. See about related data.

The American Community Survey (ACS) asks 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. The state-to-state migration flows are created from tabulations of the current state (including the District of Columbia) of residence crossed by state of residence 1 year ago.

State of the States: 2010-2015

.. examining the how, why and where of population change by state from 2010 to 2015. This section provides an overview of this topic and provides a summary of tools, interactive table and GIS project, to analyze population change by state by county, using latest Census Bureau estimates data through 2015. These data are used by ProximityOne to develop/update annual national state and county demographic-economic projections. See schedule of related 2016 updates.

Examining Population Components of Change
Population change can be examined in terms of components of change. There are three components of change: births, deaths, and migration. The change in the population from births and deaths is often combined and referred to as natural increase or natural change. Populations grow or shrink depending on if they gain people faster than they lose them. Examining a region’s unique combination of natural change and migration provides insights into why its population is changing and how quickly the change is occurring.

State-to-State Geographic Mobility: Migration Flows

.. migration data are one of the key components (births, deaths, migration) in estimating and projecting population using model-based methods.  It is the most challenging component of population change to project/forecast.  Migration data that we can “observe” are important in determining how migration has been trending and how it might change in the future for any given state or sub-state area. State-to-state and county-to-county migration flows data are important in their own right. These data tell us about where the population is moving to or from and can help develop insights into the “why” of migration from one area to another … and learn about net migration flows.

In 2013, there were an estimated 548,034 people who moved from a residence 1 year earlier, in a different state, to Texas. Texas experienced the largest number of movers (inflows) from other states among all states. 66,318 of these movers were from California. Use the interactive table to examine similar characteristics for any state. These data are based on the 2013 American Community Survey. See related data. See the related Web section for more detail about topics reviewed here and interactive access to migration data.

Visual Analysis of Mobility Patterns
The above view shows patterns of New York state outmigration by destination state. See inset legend. Note the legend shows only those states that account for 2% or more of New York out migration. Florida is the largest New York 2013 out migration destination state with 55,419 movers from New York to Florida. Intervals/colors could be changed to any configuration. The label shows total New York state out migration for that state. Expanded view shows detail more clearly. See this related view that shows a zoom-in to east coast area.

More About These Data
The American Community Survey (ACS) asks 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. The state-to-state migration flows are created from tabulations of the current state (including the District of Columbia) of residence crossed by state of residence 1 year ago. An important reason to use the ACS data to examine migration patterns is because related attributes of the population can also be studied. By using the ACS Public Use Microdata Samples (a sample of individual respondent records), we can also examine patterns of state to state movers who are of a specific race/origin, age group, educational attainment, employment status and many other attributes. In addition, since the ACS data are collected/tabulated annually, these data also provide a means to examine migration trends.

Using the Interactive Table
Use the interactive table to view, rank, query and compare states based on origin and destination of movers. The following graphic illustrates use of the interactive table to rank California movers (rightmost column) descending order by migration destination state. The blue highlighted cell shows that there were 66,318 movers from California to Texas during 2013. It is easy to see the top destination states for any state by clicking the header cell for a state of interest and sorting in descending order.
