Which 10 ZIP Codes in Hillsborough County grew the most from 2010 – 2020?

October 2021 – From 2010-2020, the Hillsborough County’s population grew 20% to 1.5 million residents[i]. Back in August, the Census Bureau released its first batch of data. Data releases will continue through 2022. Since this data is at the Census block level, we can look at population dynamics in small areas (e.g., ZIP Codes). There are 58 ZIP Codes wholly or partially inside Hillsborough County.

From 2010-2020, population growth looked very different across these ZIP Codes, ranging from 0.18% (33603 in Riverside Heights/Egypt Lake) to 93% (33598 in Balm/Wimauma). Average and median ZIP Code population growth were 25% and 18%, respectively. Out of the 10 ZIP Codes that grew the fastest, seven are in South County (e.g., 33570, 33572, and 33573). The rest are in Downtown Tampa, Brandon, and Lutz. These 10 ZIP Codes attracted 53% of all new residents to the county.  Their growth ranged from 41% in 33548 (in Lutz) to 93% in 33598 (in Wimauma) with an average growth of 63%. As expected, for ZIP Codes that straddle the Urban Service Area (USA) boundary (e.g., 33570, 33579, 33598), most of the new population moved within the USA (See Figure 1 for details).

Map shows 2010 population estimate in orange and new resident through 2020 in yellow for the fastest growing ZIP Codes in Hillsborough County. These ZIP Codes are: 33547 33548 33570 33572 33573 33578 33579 33598 33602 33619 In these ZIP Codes, population growth ranged from 41% and 93%. Average growth was 63%.

In terms of additional growth through 2045, countywide population is expected to increase 31% to 1.9 million persons. At the ZIP Code level, expected growth ranges from 2% (33634 in Town and Country) to 251% (33565 in Plant City). Average countywide growth is 45% and the median growth is 22%.

Amongst the fastest growing ZIP Codes since 2010, additional growth through 2045 ranges from 6% through 119% (See Figure 3 below). The average is 42%. Two of these ZIP Codes are expected to more than double their population (i.e., 33602 in downtown Tampa and 33598 in Balm/Wimauma). One of four expected new residents (122,718 persons) are expected to move to these ZIP Codes.

To conclude, the 58 ZIP Codes in Hillsborough County have grown an average of 25% since 2010.  The seven fastest growing ZIP Codes are in South County. Their population grew between 41% and 93%. Most ZIP Codes in Hillsborough County will see significant population growth through 2045 (averaging 45%). Countywide, five ZIP Codes will see their populations at least double through 2045 (i.e., 33527(Dover), 33565 (Plant City), 33584 (Seffner), 33592 (Thonotosassa), 33598 (Wimauma), and 33602 (Tampa).
