The authors use Bongaarts's fertility preference measurement methodology to examine and compare changes in fertility preferences in Colombia, Costa Rica, the Dominican Republic, Ecuador, Jamaica, Peru, and Trinidad and Tobago over the period 1975-1989. "The trends of observed and desired fertility are examined at the national level and by level of education and rural-urban place of residence. The data used comes from fertility surveys....such as the World Fertility Survey (WFS) and the Demographic and Health Survey (DHS). The analysis suggests that the changes in fertility between the dates of the two surveys...are not due to changes in desired fertility, but mainly to differences in the degree to which fertility is controlled to coincide with desired levels.... Both the WFS and the DHS show that unwanted fertility was significant in all countries, specially in the lower socioeconomic strata." (SUMMARY IN ENG)
