Unplanned pregnancies account for a substantial proportion of births in Kenya and can have a variety of negative consequences on individual women, their families, and the society as a whole, says a paper from the Department of Social Statistics, University of Southampton. The paper shows that unplanned childbearing in Kenya is associated with a number of factors, including urban/rural residence, region, ethnicity, maternal education, maternal age, marital status, birth order, length of preceding birth interval, family planning practice, fertility preference and unmet need for family planning.
