Distance between vulnerable tracts by vulnerability component.

Heat Vulnerability Index (HVI) and Components	Heat-vulnerable tracts^a	Vulnerable Tracts < 0.5 miles, N (%)	Total Population	Percent Population < 0.5 miles	Distance to nearest cooling center (miles)

					Average	Median

Cumulative HVI	961	494 (51.4%)	3,682,132	48.2	2.43	0.46
Factor 1-Language	898	366 (40.8%)	3,997,812	38.0	2.83	0.87
Factor 2-Socio-economic	1096	480 (43.8%)	4,010,092	41.9	4.71	0.74
Factor 3-Urban	1367	596 (43.6%)	5,374,005	40.2	1.94	0.70
Factor 4-Elderly	1209	419 (34.6%)	4,797,244	34.2	4.47	1.18

Heat-vulnerable tracts defined as tracts with Cumulative HVI Score ≥ 15 or Component scores ≥ 4.
