This data note looks at national and state-by-state Medicaid and CHIP enrollment data through January 2022, when the daily number of new COVID-19 cases reached the height of the pandemic due to the Omicron variant. After declines in enrollment from 2017 through 2019, preliminary data for January 2022 show that total Medicaid/CHIP enrollment grew to 87.0 million, an increase of 15.7 million from enrollment in February 2020 (22.1%), right before the pandemic and when enrollment began to steadily increase (Figure 1).
