Definitions: The total number of preventable deaths to teens age 15 to 19 for a five-year period by town or county. Preventable deaths are defined as deaths from accidents, suicides, and homicides. Rates per 100,000 teens are calculated as the number of preventable deaths of teens age 15 to 19, divided by the total number of teens in this age group, then multiplied by 100,000. The total number of teens age 15 to 19 is estimated by applying the 1990 or 2000 Census proportions to the population estimates from the Connecticut Department of Public Health for those years. Rates for towns in which fewer than five teens died are not calculated because of the unreliability of calculations based on small numbers.
Please note: The number of teen deaths each year in most towns is too small to calculate to obtain a valid rate each year. For events with small numbers and for reasons of confidentiality, it it most important that rates be calculated using a five-year time period.

LNE = Low Number Event. Rates for towns in which fewer than five incidents occurred are not calculated because of the unreliability of small numbers.
Note: Maps use the natural break classification method, which reflects patterns
in the data by dividing the map into naturally occurring groups. Using statistical tools, this method
determines cut-off points for each group by identifying large gaps in data values.
