Centre for Actuarial Research (CARe) A Research Unit of the University of Cape Town The Centre for Actuarial ResearchandDemographic teaching and research in South Africa
Outline • Background and overview of CARe • History • Focus areas • Research outputs • Demographic teaching and research • UCT • Other universities in South Africa (briefly)
History of CARe • Started in 2001 • Three directors and one RA • Four strands (Health care financing, Social security, Demography, HIV/AIDS modelling) • Evolved into current structure: • Director • Three Senior Lecturers • Two Senior Researchers • Two Research Assistants and post doctoral fellowships
History of CARe • Focus now on AIDS modelling and demography • Unique, in that we have a teaching programme embedded in a research unit • reflects the awkwardness of locating technical demography as a discipline • “demography is an interdiscipline” Stycos (1989) • but also the importance we attach to the symbiosis between research and teaching • it works well
Focus : Demographic research • Demographic research and teaching • Director, Senior Lecturers and post-doctoral fellows are the ‘demographers’ • Although we each have interests in the focus areas of others, we each have specialist interests: fertility (TM) and mortality and population projections (RD) • Much research involves estimation and interpretation of results, but we have particular interests in interrogating and improving the methods of estimation and in devising methods for interrogating data quality • We are all responsible for teaching and supervision
Demographic research • Overarching themes • Improvement of old, and derivation of new, methods of estimating demographic parameters from limited and defective data • Derivation of population estimates • Production of fertility and mortality rates for SA • Mortality • Reconciliation of mortality data from Southern and Eastern Africa with estimates from the UN • Establishing impact of HIV/AIDS on mortality and interventions on that • Fertility • Patterns of childbearing in Southern and Eastern Africa • Methods and motives for contraceptive use • Migration • Internal and international migration in SA
Focus • HIV/AIDS modelling • Leigh Johnson and RD are involved in developing and using the HIV/AIDS models • HIV/AIDS research has been contentious in South Africa (possibly none more so than the production of estimates of the numbers of infected, sick and dying) • The model we work on derives from and is released under the auspices of the Actuarial Society of South Africa (ASSA) • More on this in another session
Focus • Other activities • Research consulting • Recent: NACA/UNDP Botswana, Gauteng government • Past: BER, Stats SA, PGWC, Cape Metro, SAAVI, various small contracts • Research seminar series • Around 12-15 a year, 4-6 international visitors p.a. • This year so far: Wolfgang Lutz (IIASA, AAS), Gigi Santow, Ian Timaeus (LSHTM) and Michael Bracher • Others: e.g. Simon Gregson (Imperial, Zim MRC), Bob McCaa (U Minnesota), Tim Dyson (LSE), Sam Clark (U Washington), David Lam (U Michigan), Simon Sreter (Oxford), Cedeplar • Publication of monographs, occasional papers, etc • SAJD
Research highlights • Significant contributions (with MRC) to the definitive work on burden of disease and cause of death in South Africa • Publications in highly rated international journals: Population Studies; Demographic Research; Journal of Southern African Studies; Sexually Transmitted Infections; AIDS • Significant monographs written for Stats SA (2) and the Medical Research Council (2), one of which has been downloaded more than 20 000 times (by the time counting stopped!)
Funding • Four main sources: • Significant research contracts • Other research contracts to undertake small projects • Short courses (although primary concern is to cross-subsidise participation) • Funding from Mellon and Hewlett Foundations to support the development of (particularly teaching of)technical demography – posts and scholarships
Collaboration • Africa Centre (DSS in northern KwaZulu-Natal) • Memorandum of Understanding • projects: modelling, validation • Graduate student from UCT working there as demographer • Dikgale (DSS in Limpopo province, SA) • LSHTM – Ian Timæus • University of Washington – Sam Clark & Adrian Raftery • Cedeplar
Collaboration • Others • Wolfgang Lutz (IIASA) • UN Population Division • UNAIDS Reference Group on Estimates, Modelling and Projections • South Africa • MRC, HSRC, Stats SA, SAAVI • DoH, DoSD, National Treasury • TAC, C A S E, Children’s Institute, DataFirst, Saldru, BER • ASSA • Other Mellon-funded University programmes (Wits, UKZN) • Other • INDEPTH, Other Hewlett-funded institutions in Africa (Wits, University of Nairobi, Gold Coast)
Demography at UCT • Demography in South Africa was highly politicised during the apartheid era • Seen to be politically compromised • No teaching or training (and very little research) into demography at English-speaking universities in South Africa until after 1994 • Then UNFPA funding of several institutions – not UCT - followed by grants from the Andrew W Mellon Foundation to three institutions in South Africa (KZN, Wits, UCT) • Regarded as a ‘scarce skill’ in South Africa
Demography at UCT • At UCT, some research had been done on demography in the late 1980s and 1990s • historical demography, using mission station church records to reconstruct mortality trends at the end of the 19th century • derivation of national life tables • leadership role in the development of the ASSA Aids and demographic model from the mid-1990s on • collaborative work with the MRC. • … but no structured teaching, training or research programme
Demography at UCT • The Mellon grants changed this • 1st grant (1998-2001) largely used to run a detailed demographic, economic and anthropometric study in the Southern Cape • First trained demographer employed in 2000, a joint appointment between the School of Economics • 2nd grant (2001-4) split, broadly, between CARe (teaching) and Saldru (research) • MPhil in demography launched in 2003 • First doctoral students enrolled • 3rd Mellon grant, 2004-7 continues in same vein • Mellon funding ends in 2007
Demography at UCT • Hewlett Foundation grants • Further support for demographic teaching, training and research
Rationale for CARe’s approach • An audit of demographic training in Southern and Eastern Africa, conducted in 2004-5 • Focus is unique in the region • The only institution engaged in teaching, training and research in technical demography • Skills in technical demography are being lost, due in part to the post-Cairo consensus which prioritises reproductive health over demography • But there is still a strong need for these skills to estimate demographic parameters, and to assist with planning; but data are not getting any better
Rationale for CARe’s approach • Strong need for a (small) cadre of technically-sound demographers, trained to • Carefully assess and analyse local census and survey data, to maximise the utility of this information in informing public policy • Estimate demographic parameters and project populations • Train future generations in these skills
Programmes offered • PhD in demography • UK model – 3 year independent research • Coursework to ensure foundational knowledge • Increasingly moving to a 1+3 model • MPhil in demography • 18+ months, coursework and dissertation • Emphasis on technical skills • MCom in economics and demography • Resuscitated and relaunched in 2005 • BSc in statistics and demography • Designed as a long-term feeder for the MPhil

Other training, data access and collaborative opportunities at CARe • Short course on demographic modelling using the ASSA model • Week-long course run every June-July • Data First • Resource centre dedicated to archiving census and survey data • Holds most African DHS data, as well as large amounts of census data • Visiting demographers • CARe has resources to host visiting demographers for short-term visits (<3 months) to assist in data analysis and/or interpretation
Demographic teaching and research elsewhere in South Africa • Mellon-funded institutions (-2007) • U. KwaZulu-Natal: focus on population-poverty links • U. Witwatersrand: focus on public health and migration. Also funded by Hewlett (2005-) • Other institutions • University of the North-West • University of the Western Cape • Most of these institutions are relatively weak in the area of formal or technical demography
