COVID-19 Town-Level Case and Test Positivity Rates in Connecticut

16 columns of data track biweekly COVID-19 case rates and test positivity for towns in Connecticut. The dataset is updated weekly by the Connecticut Department of Public Health and contains information starting from June 16, 2022. Data for towns with fewer than 5 cases or positive tests in a week are suppressed to protect confidentiality.

Use Cases

• Model the relationship between Town population and COVID-19 cases per 100k population over 2-week period to identify demographic risk factors.
• Analyze trends in Percent test positivity by Town across successive Report period start date and Report period end date intervals.
• Compare case burden between towns by ranking Total cases over 2-week period and Cases in Week 1 versus Cases in Week 2.
• Assess testing volume and disease spread by correlating Total tests with COVID-19 cases per 100k population over 2-week period for each Town.

Strengths

• Includes 16 specific columns such as Town, Town population, and Percent test positivity for detailed analysis.
• Data is updated weekly with a clear update schedule and a last metadata update recorded on 2023-08-02.
• Provides multiple calculated metrics including rates per 100,000 population and a two-week percent positivity.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data for towns with fewer than 5 cases or positive tests in the past 7 days is suppressed, creating gaps for small communities.
• Metadata completeness is limited; actual data quality and completeness for historical periods require manual inspection after download.
