Archived California COVID-19 Metrics by County and State

California COVID-19 time-series data includes metrics on cases, deaths, testing, age, race, ethnicity, and gender, aggregated by county and state. The dataset is archived and was last updated on December 1, 2023, with weekly updates prior to archiving. It encompasses data from state and federal prisons, ICE facilities, and tribal communities.

Use Cases

• Analyze COVID-19 death trends by county and demographic factors like age and race using archived death data.
• Model case positivity rates by county using historical cases and testing data, accounting for reporting lags in test results.
• Examine demographic disparities in COVID-19 outcomes by analyzing cases and deaths segmented by ethnicity and gender.
• Track the progression of the pandemic across California counties using time-series data on cases and deaths.

Strengths

• Includes multiple demographic dimensions such as age, race, ethnicity, and gender for granular analysis.
• Covers data from institutional populations including prisons and tribal communities, providing broader coverage.
• Provides weekly time-series updates until its archival on December 1, 2023.

Limitations

• Dataset is archived and no longer updated as of December 1, 2023, limiting analysis to historical periods only.
• Test data columns may show 'NONE' for recent dates due to reporting lags, which can be misinterpreted.
• Death data sources changed in 2023, introducing a potential break in consistency for time-series analysis.
