Resulting Data for AnalysisAs a result <strong>of</strong> restricting the study to metropolitan areas, as well as reductionsfor lack <strong>of</strong> geographic coding, unduplication, and accuracy, the total number <strong>of</strong>subsidized units was reduced from 5,575,139 in the original HUD database to4,026,787 units for this study. <strong>The</strong>se units are located in 51,118 census tracts in 331MSA’s. Public housing comprises 872,810 <strong>of</strong> the units (21.7 percent <strong>of</strong> total); othersite-based units comprise 1,254,505 units (31.2 percent); LIHTC comprise 716,915units (17.8 percent); and vouchers comprise 1,182,557 units (29.4 percent).
