Choropleth maps of health outcomes using an equal numerator classification. In an equal numerator classification, approximately the same number of health outcome events are associated with each color representing a class interval in the map. This classification portrays the spatial distribution of the percent of low birthweight births by town in Connecticut in the upper-left diagram and portrays the spatial distribution of Lyme disease per 100,000 population by town in Connecticut in the upper-right diagram. A numerator/denominator cumulative frequency legend associated with each map is presented beneath the respective map.
