Presentation Outline Need for Population Projections by education Our Approach Applications
Need for population projections by age, sex and educational attainment Changing definition of education categories in national time series – Standardization needed – Categories based on ISCED Absence of time series data by age and sex Education being an important explanatory variable in many processes – fertility, mortality, migration, vulnerability analysis, conflict, …. Future planning, target setting (MDG, EFA) etc….
Reconstruction of past education distribution by age and sex Start with 2000 distribution as base year – 5 yearly age groups – Males/Females – 4 education categories Less than one year of Primary education More than one year of Primary education Completed lower secondary education Completed first level of tertiary education
Reconstruction Move backwards – 5 year step – With differential mortality and migration Positive Correlation between life expectancy and educational attainment At age 15: a difference of 5 years – Demographic Multi-state Cohort Component Method used Four states of education with backward education transitions from higher level to lower level Moving backward along cohort line – Matching Population Distribution with the UNPD’s estimates
Singapore
Nepal
Projections Same starting distribution 2005 – 2050 Future Demographic Trajectories – UNPD – World Population Prospects 2006 – Eurostat – Own Estimates for few non European low fertility countries Future Education Trajectories – Baseline – Global Education Trend Scenario – Other scenarios ranges from Most rapid educational expansion – Fast Track Scenario Assumptions of constant enrollment ratios and numbers
Projections Multi-state – Transition between different levels of education Cohort Component method – Projections along cohort lines 123 countries of the world
Global Education Trend Scenario Baseline Trend, Business as Usual etc. Based on the past education trend – All countries pooled together – Fitted using cubic spline General trend of improvement Plausible medium-term scenario
Fertility Differential
Mortality Differentials Life expectancy at age 15 – 5 years difference between the tertiary educated and those with no formal education Migration – Net Migration (WPP 2006) – Own calculation – age-sex distribution – By education Negative Net migration – sending country’s distribution Positive Net migration – pool of all sending countries’ distribution

Projection Results
Using the data Economic analysis: Human Capital and Economic Growth – (Lutz et al, 2008 in Science; Sanderson and Striessnig, 2009) Analysis of Youth Bulges and Conflict (Barakat & Urdal, 2008) OECD: Projected tertiary educated population in 2030 in a selected number of non-OECD countries. Eberstadt, Nicholas: Economic Outlook for Central Asian states, China, Russia, Iran, Turkey.
Using the data Estimating effects of educational attainment on economic growth Improving economic growth forecasts by assessing the interactions between education and demographic trends Studying the effect of human capital on health indicators Assessing the effects of education on democratization processes and political institutions
Possible Uses Check feasibility of international education targets Analyze the role of education in: – Adaptive capacity to environmental disaster – Vulnerability analysis
Future plans Country or Region specific differentials Country or Region specific Education Scenarios Adding more countries Link education and disability (health) status for projections Link education and place of residence (urban/rural) status for projections
