Evaluating COVID-19 Data Means Reading the Numbers and Their Limits

The COVID-19 pandemic produced huge amounts of data, from case counts to vaccination rates.
Evaluating this data shows the pandemic's impact and how well responses worked.
Two key tools are percentage change and percentage difference.

Tip

These calculations let you compare data over time or between groups.

Percentage Change Tracks a Value Over Time

Percentage change measures how much a value has risen or fallen compared with its starting amount.
1. $$\text{Percentage change} = \frac{\text{Final value} - \text{Initial value}}{\text{Initial value}} \times 100\%$$
Use it to track how infection rates rise or fall over time.
Use it to measure gains in vaccination coverage.
