"A California survey found that, although 86% of respondents prefer single-family homes, 47% prefer a walkable, mixed use neighborhood; 49% would choose a smaller house if it provided a shorter commute; and 31% would choose a high-density neighborhood if it had convenient public transit (PPIC 2002).
A survey of Houston, Texas residents (Blueprint Houston 2003) asked, “Would you personally prefer to live in a suburban setting with larger lots and houses and a longer drive to work and most other places, or in a more central urban setting with smaller homes on smaller lots, and be able to take transit or walk to work and other places?” Fifty-five percent of respondents chose the “Central urban setting” and only 37% chose the “Suburban setting.”
The Atlanta, Georgia SMARTRAQ study found that only about 5% of homes in the region are in compact and walkable neighborhoods, and only 40% of respondents indicated that they could walk to any nearby shops and services. Yet, 20% to 40% of respondents expressed a very strong preference for the most compact and walkable neighborhoods (depending on which attributes were considered), 49% prefer a neighborhood where residents can walk to nearby shopping, and 55% prefer a community with smaller lots if it offers shorter commutes. About a third of metro Atlantans living in automobile-dependent, suburban locations indicate they would prefer a more walkable environment but traded it off for attributes such as affordability, school quality, or perception of crime. This suggests a significant undersupply of accessible, walkable neighborhoods.”
