Table 2.

Number of migrant households in out-flows and in-flows to disaster-affected coastline counties, IRS county-to-county migration flows data for tax filing years 1999–2004 (pre-disaster) and 2007–2009 (recovery)

Total flow size between disaster-affected coastline counties and: (Number of migrant households)	Out-Flows			In-Flows
	Pre-disaster	Recovery	% Change	Pre-disaster	Recovery	% Change
All counties	131,411	137,424	4.6	121,310	144,854	19.4
Disaster-affected coastline counties	49,959	54,030	8.2	49,959	54,030	8.2
Nearby counties	28,711	31,338	9.2	23,727	30,864	30.1
Distant counties	52,742	52,056	−1.3	47,624	59,960	25.9
All counties (urban)	126,576	132,684	4.8	116,920	140,062	19.8
Disaster-affected coastline counties (urban)	49,595	53,634	8.1	49,595	53,634	8.1
Nearby counties (urban)	26,018	28,587	9.9	21,079	27,969	32.7
Distant counties (urban)	50,896	50,400	−1.0	46,247	58,459	26.4

Notes: Total out-flows are equivalent to total in-flows for disaster-affected coastline counties because the group of sending counties is the same as the group of receiving counties; the in-flows and out-flows are the migrant exchanges among this group of counties.
