State of New Jersey – 2004

The primary objective of this survey was to determine the extent, rate, composition and probable origin of litter along New Jersey’s streets, highways and other locales, using a unique stratified random sampling model. This model accounts for factors that influence litter, such as roadway type and adjacent land use, traffic volume, weather, income, county population size, distance to the nearest city, and the type and duration of litter control program effort.
