Use Cases

• Analyze town-level disparities in Case rate per 100k using Town and population-derived statistics.
• Model the relationship between Number of tests and Number of positives to estimate test positivity rates by municipality.
• Track the progression of Probable cases versus Confirmed cases over time using Last update date.
• Assess mortality impact by comparing Confirmed deaths and Probable deaths across different Town numbers.
• Calculate testing coverage by comparing People tested and Rate tested per 100k across towns.

Strengths

• Contains 16 columns of town-level metrics including case rates and death counts.
• Data is updated daily and spans from the beginning of the pandemic.

Limitations

• Data for towns with fewer than 5 cases or positive tests in a 7-day period is suppressed, creating gaps.
