Maryland COVID-19 Confirmed Deaths by Age Group, Reported Daily and Weekly

Cumulative confirmed COVID-19 deaths among Maryland residents are reported by 10-year age brackets, including an 'Unknown' category. The data was reported daily by the Vital Statistics Administration until April 27, 2023, after which updates changed to weekly, and the dataset was deprecated on October 10, 2025. It includes columns for age groups from 0-9 to 80+ and a DATE field for tracking the cumulative count over time.

Use Cases

• Analyzing temporal trends in COVID-19 mortality by age group using the DATE and Age_* columns.
• Calculating the proportion of deaths in specific age cohorts (e.g., Age_60_to_69, Age_70_to_79) relative to the total.
• Tracking data completeness over time by monitoring the Age_Unknown column.
• Comparing mortality impact across different adult age groups (e.g., Age_40_to_49 vs. Age_50_to_59).

Strengths

• Data is structured with 12 specific columns for age groups and date.
• Source is the authoritative Vital Statistics Administration of the State of Maryland.
• Clear documentation distinguishes between confirmed and probable deaths.

Limitations

• Dataset is deprecated as of October 10, 2025, and is no longer being updated.
• Row count and total size are unknown, which may limit suitability assessment.
• Data may reflect reporting lags as noted in the description, and an 'Unknown' age category is present.
