FAQ

We last gathered CDC data on February 06, 2025. We last updated the curated dataset on February 26, 2025.

In the February 07 2025 dataset, we:

• added the 2022 data;
• added metrics (seven calculated: Tscr1r, PerTscr1, PerPas1, PerNotPas1, PerPIS, Tscr1, PIS; four reported: TotPas1, TotNotPas1, TDia3, NHL3); and
• updated some sources (see Where did you get this data? FAQ below for more details).

In the February 26 2025 dataset, we corrected the PerLTF metric that in the February 07 2025 dataset was multiplied by 10 instead of the intended 100.

In previous January 30 2024 and earlier datasets, we used 2014-2020 data shared by CDC on October 13, 2022, supplemented with 2007-2020 data from CDC’s website as needed. For the February 7 2025 dataset, we reviewed the CDC website and due to data differences that we noticed, all the 2014-2020 data were replaced with data extracted from PDFs on CDC website.
