Table Variables

The following link shows a listing of table variables and associated characteristics when generating a table.

Animated Formulas

The following link shows the formulas used to calculate rates with examples.





Occurrence Data - Data allocated to the place in South Carolina where the event occurred, regardless of the usual residence of the person involved.

Rate Calculations with Small Numbers - There are variations in all statistics which are the result of chance. This characteristic is of particular importance in classifications with small numbers of events where small variations are proportionately large in relation to the base figure. As an example, small changes in the number of deaths in small population areas or in the number of deaths from uncommon causes could result in large changes in these crude rates. For this reason, rates for counties with small populations or other small bases should be used cautiously. In these tables, rates are not calculated for places of less than 2500 population or when the number of events is less than 5 for a particular category, due to the known instability of rates based on small numbers.

Residence Data - Data allocated to the place in South Carolina where the person normally resided, regardless of where the event occurred.

Population Data: The population data is obtained from South Carolina Budget and Control Board's Office of Research Statistics prior to 2004 and from National Center for Health Statistics since 2004.
