Hartford has seventeen neighborhoods that are defined by the city. However, the boundaries of these city-defined neighborhoods do not conform to the U.S. Census tracts, which are the data collection areas used here. For many reasons, data is often only available for whole census tracts. For the purposes of Hartford Trends, neighborhoods are defined as aggregation of whole census tracts. Below is a description of each whole census tract neighborhood (data collection area) and how it varies from the city-defined neighborhood. As a measure of how significant the variation is, the variation is stated as the percentage of the whole census tract neighborhood.

Asylum Hill: Census tracts 5031, 5032, 5033, and 5034
Small portions of tracts 5032 and 5034 which fall outside the city-defined boundaries of the neighborhood on the north and east include very few people, and add less than 1% to the total population. More significant is the assignment of portions on the west side of the city-defined neighborhood of Asylum Hill (tract 5036 and 5042) to the data collection area of the West End. The population of these two areas constitutes 15% of the population of the Asylum Hill whole census tract neighborhood.
