Projecting fertility by educational attainment: Proof of concept of a new approach.

ABSTRACT

The United Nations Population Division publishes fertility projections for all countries

in the World Population Prospects (WPP). These are the most widely used projections

for planning and policy implementation. Despite a substantial body of literature that

suggests education has a significant impact on fertility, these projections do not

incorporate changes in the composition of the population by level of education. We

therefore propose and implement a method that incorporates education composition

change in projecting fertility. We investigate fertility differentials by level of education,

then evaluate how education influences fertility independently; and finally, a model is

fitted to project fertility rates by education levels. In both cases, the fertility rates by

education level are then weighted by the IIASA educational attainment distributions to

get the national fertility rates. These national fertility rates are in turn validated against

the WPP fertility rates to evaluate how good the proposed method works. Fertility is

high among the less educated relative to educated women. Education proves to be an

important driver of fertility decline in Southern Africa. The proposed model is a good

fit for countries with sufficient DHS data. However, there are other sources of data that

are available, for example, the census data but we could not rely on them since they only

give summary information. Validation was done to evaluate how good the model is

working. This exercise produced consistent results with the observed fertility estimates.

The percentage difference between the projected and WPP fertility estimates varied

from 1 to 5 percent in Lesotho, Namibia and Zimbabwe. In conclusion, the model can

also be used for other countries. Furthermore, education composition change should be

considered when projecting fertility since it has proven to be a significant driver of

fertility change. Data quality and availability issues were a major limitation to our study

and in future should be improved.
