Re: [CTPP] Changes in Workers per HH and Vehicles per HH (long post)

Workers/Households appears to be a very static statistic! According to "Journey-to-Work Trends in the United States and its Major Metropolitan Areas, 1960-1990" (FHWA, Nov. 1993, p. 2-2), the figure changed little over three decades 1960-1990: 1960: 1.22; 1970: 1.21; 1980: 1.20; 1990: 1.25. Given the large changes in household structure during this period (large increases in divorce, women in workforce), this consistency is very remarkable. I interpret the flat trend as a sign of a fundamental requirement for the support of a household. The figure Chuck reported for 2000 (1.24) continues the trend and is therefore not surprising to me. Therefore, I expect the statistic to stay in the 1.20 to 1.25 range for the foreseeable future. Rob Robert B.
