Green Space: Survey respondents were asked to identify the variety of green spaces, including athletic fields, city parks, public gardens, trail systems and waterfronts, along with any additional spaces. This question was designed to elicit the variety of outdoor amenities available and was scored on the total number of different types of green spaces present. Scoring also considered the percentage of overall city area occupied by green space.

Public Health: Scores were based on Robert Weinhold's rankings of the 125 healthiest U.S. cities as published in the March 2004 Organic Style.

Recycling: Survey respondents were asked to indicate which items their city recycles from a list that included aluminum, cardboard, glass, hazardous materials, paper, plastic, tin and other. Cities that had more then seven categories of recyclable items were given the highest scores.

Socioeconomic Factors: Having considered affordability in 2005, this year The Green Guide expanded the analysis to consider the impact of income on the ability of urban residents to lead healthy lives. Cities scored well for having less than the national average of families and individuals earning below the poverty rate. Participants also gained points for having a city minimum wage and for the availability of housing affordable to families earning the area's median income according to the National Association of Home Owners' Housing Opportunity Index.

Transportation: Wishing to recognize efforts to get people out of their cars (reducing greenhouse gases, traffic congestion and smog), we asked survey respondents about the transportation options available, including bicycle paths, bus systems, carpool lanes, dedicated bicycle lanes, light rail, sidewalks/trails and subways. As a follow up to this, we also asked about the percentages of residents who used public transportation, rode bicycles to work and carpooled.

Water Quality: In order to assess this complicated factor, we drew on data from the EPA's Safe Drinking Water Information System (SDWIS) and noting violations of the Safe Water Drinking Act, with the greatest weight given to health violations.

Each of these factors was equally weighted, with a maximum score of 1 point per criterion, to create an overall maximum possible score of 11 points, though only one city we looked at, Eugene, Oregon, scored 9 or better. Unfortunately due to lack or response or incomplete surveys, some cities that might have ranked higher are not included here.
