We’re excited to celebrate #GISday. The State Data Center uses Geographic Information System (GIS) technology almost every day to help communicate information about Tennessee, our communities and changes occurring across the state.

We used historic census data from the IPUMS National Historic GIS to look at some basic housing unit trends in Nashville/Davidson County including housing unit growth between 1990 and 2020 and changes to housing vacancy rates over the same period.

Population data is used to calculate infection rates and in cooperation with the Census Bureau, we’ve compiled new age data for all 95 Tennessee counties to help improve the accuracy of age-based COVID-19 rates.

Public Use Microdata Areas, or PUMAs, are statistical with no fewer than 100,000 people for which anonymized, individual Census responses are released. In late 2021, the State Data Center will lead an update to Tennessee’s PUMA boundaries.

According to 2018 census data, there were over 435,000 veterans living in Tennessee comprising about 8.5% of the state’s population. We’ve compiled links to state and county-level data to help ease the search for this information.

2020 Census results are confidential—but what if today’s computing power could be harnessed to reconstruct responses and re-identify individuals who responded? New procedures to protect privacy are important, but they can also affect the accuracy of the published results.

Want to see how the 2020 Census temporary hiring is affecting employment in your area? A new dashboard from the Tennessee State Data Center shows just how many temporary workers are employed in each state across the nation.

In October, we released the 2018-2070 Boyd Center Population Projections. To help facilitate both access analysis, we published a new population projections dashboard earlier this month.

The new projections incorporate the latest births, deaths and current population estimates to update the projections last released in 2017.

Counties and places with a population of 65,000 or more are included in this first batch of data. The 2014-2018 5-year ACS release in December will include the remaining cities and counties, as well as tracts and block groups.
