Net Domestic Migration · District of Columbia

## What this measures

Net domestic migration for District of Columbia: the number of people who moved to District of Columbia from elsewhere in the United States, minus the number who moved from District of Columbia to another state, over twelve months from July 1 to June 30.

## Why it matters

Moves between states follow jobs, housing costs and taxes, and they carry workers, spending and tax bases with them. A state that keeps gaining people from the rest of the country grows its workforce without relying on births or immigration; one that keeps losing them has to replace them.

## How to read it

People per year. A positive reading means more Americans moved in than moved out; a negative reading means more left. Each point is dated July 1 of the year in which the twelve months end. Across all fifty states and DC the readings add up to zero, so one state's gain is another's loss.

## What it does not say

It is an estimate built from tax returns, Medicare enrollment and other administrative records, and each December's new vintage revises every year back to the last census. It leaves out moves to and from other countries (census.pep.net_international_migration.dc) and says nothing about who moved or why. The series starts with the year ending June 2021: the three months after the 2020 census are a partial period and are not published.
