Study Area–ZIP Codes . ZIP codes are also used in the report to utilize available federal datasets that are structured along ZIP code tabulation areas (ZCTAs) rather than Census tracts. ZCTAs closely match postal ZIP codes in most areas and provide an additional means for decomposing a broader region into smaller localized areas. Census ACS data is generally tabulated by both Census tract and ZCTA. Throughout the remainder of the report, ZCTAs are referred to simply as ZIP codes. The downtown study area is typically defined using four ZIP codes – 73102, 73103, 73104, and 73106. The general borders of the combined area are shown in Figure 10 and include Pennsylvania Avenue to the west, 30 th Street to the north, Reno Avenue to the south, and just east of I-235 to the east. ZIP code 73104 extends east of I-235 to capture the OU Health campus. Three of the four ZIP codes – 73102, 73103, and 73104 – are closely aligned with areas covered by the basic downtown study area shown in Figure 7. ZIP code 73102 is closely aligned with the central business district; 73103 is centered over Uptown; and 73104 includes the OU Health campus and Bricktown.
