Note: All case counts shown are expected census tract-level case counts. Any numbers greater than 1 have been rounded to the nearest whole number and are referred to in the text by the complete value. Total population 5000 persons is the recommended aggregation scheme for common outcomes. Sub-population aggregation thresholds were as follows: 1000 persons (333 persons 0–4 years old and 667 persons 65+ years old); 2500 persons (833 persons 0–4 years old and 1667 persons 65+ years old); and 5000 persons (1667 persons 0–4 years old and 3333 persons 65+ years old).
