Data from the Annual Housing Survey indicated that 22% of all employed United States household heads commuted to a county different from that in which they lived in 1975. Commuting was more prevalent among men than among women and slightly higher for whites than for Blacks. Commuting tended to increase until age 25-34 and then to decline after age 45. Commuters had a generally higher income level than did noncommuters. Education was directly associated with commuting in metro areas but was generally negatively associated in nonmetro areas. Those who had recently moved from metro areas into nonmetro areas commuted at a rate double that of other nonmetro heads. Nonmetro-to-metro commuters outnumbered metro-to-nonmetro commuters. Median time spent going to work was 14.5 minutes for nonmetro heads and 21 minutes for metro heads. Though automobile travel to work dominated in all areas, there was greater use of public transportation in metro areas and more walking or riding with others in nonmetro areas. Survey data point out groups that will be most affected by continued high prices of gasoline and other costs of commuting and the need for the development of alternatives to individual travel. Detailed tables are included in this study. (CM)
