considerably greater proportional changes, with national averages <strong>in</strong> <strong>2025</strong> rang<strong>in</strong>g from 28%<br />
higher (65-69 women) than 1995 levels to 113% (85+). The greatest proportional <strong>in</strong>creases<br />
occur <strong>in</strong> the 85+ women <strong>in</strong> all regions, reach<strong>in</strong>g 122% and 142% <strong>in</strong>creases <strong>in</strong> the Northeast<br />
and South respectively. In 1995, 65.1% of women 65-69 were drivers nationally, with that<br />
percentage ris<strong>in</strong>g to 83.6% by <strong>2025</strong>. In the West, 92.9% of women <strong>in</strong> that age group are<br />
projected to drive by <strong>2025</strong>, but only 64.1% <strong>in</strong> the Northeast (which also had the smallest<br />
percent <strong>in</strong>crease over the period). Only 19.2% of women 85+ drove <strong>in</strong> 1995, and nearly<br />
41.1% are projected to drive by <strong>2025</strong>, with the highest proportion <strong>in</strong> the Midwest at 52.5%<br />
and the lowest <strong>in</strong> the Northeast at 22.2%.<br />
Tables 6.2 and 6.3 show the national and regional contributions of growth <strong>in</strong> <strong>in</strong>come<br />
and labor force participation (LFP) to the projected growth <strong>in</strong> the percentage of drivers<br />
between 1995 and <strong>2025</strong>. Income is the predom<strong>in</strong>ant, identifiable social determ<strong>in</strong>ant for men,<br />
but the <strong>in</strong>fluence of the time trend is dom<strong>in</strong>ant for women of all ages. The effect of <strong>in</strong>come<br />
decl<strong>in</strong>es steadily by age group for men, and generally but not uniformly for women. The<br />
effect of LFP growth is m<strong>in</strong>imal on women. In Table 6.3, the contribution of <strong>in</strong>come growth<br />
<strong>in</strong> excess of 100% and that of LFP growth <strong>in</strong> the negative range for northeastern and southern<br />
men <strong>in</strong> the 65-69 age group reflects negative time trends <strong>in</strong> those two groups. These tables<br />
also show the enormous contribution of the pure effect of time, an <strong>in</strong>dist<strong>in</strong>guishable<br />
comb<strong>in</strong>ation of technological and <strong>in</strong>stitutional changes extrapolated from the past but<br />
dampened to reflect previous slow<strong>in</strong>g trends. The <strong>in</strong>terpretation of these magnitudes and<br />
signs is that, if it were not for the effect of the regional time trend, <strong>in</strong> both cases the driver<br />
percentage <strong>in</strong> <strong>2025</strong> would be substantially higher than it is with the time trend.<br />
