It's a statistical average. 

In 1990, the peak year:

1.6M (abortions per year) * 85 (life expectancy) / 140M (female
population) = 1.0

In 2005:

1.2M  * 85 / 150M = 0.7

Confirmation: 

1990: 27 (abortions per 1,000 women aged 15-44) * 30 (years) = 0.8
2005: 19 * 30 = 0.6  

This set is lower because most women having abortions are aged 15-25.
Including 35-44 in
the statistic produces an artifically low rate.
