District residents are decamping to the suburbs, while more people are settling in the farther reaches of Virginia and Maryland, according to Census data released Thursday.

More than 40,700 residents left D.C. in the first four years after the 2000 Census, roughly 10,176 per year, according to the data. Between 1990 and 2000, 146,480 people moved out of D.C., so the trend is slowing. The figures do not include births, deaths or immigrants, which tend to offset the so-called “outmigration” numbers.
