Other IUSSP-Activities
IUSSP Plenary session at the 2008 Annual Meeting of the Population Association of America (PAA) in New Orleans, USA, 16 April 2008
The IUSSP Plenary at the 2008 PAA was dedicated to the topic: “Are Policies Responsive to Adolescents’ Sexual and Reproductive Transitions and Needs?” The session was organized by Fatima Juarez, Chair of the IUSSP Panel on Adolescent Life Course in Developing Countries and featured three speakers: Ruth Dixon- Mueller – “How Young is ‘Too Young’? Comparative Perspectives on Adolescent Sexual and Reproductive Transitions”; Shireen Jejeebhoy – “Individual Agency: Is the concept useful for the study of transition to adulthood, and how does it relate to policy? The case of India”; and John Santelli, – “Responsiveness of US policies and programs to adolescents’ sexual health needs: Similar or different to other countries?”.
IUSSP session on "Recent Trends in Demographic Modelling" at the 56th Conference of the International Statistical Institute
Lisbon, Portugal, 28 August 2007.
John Cleland organized this session on behalf of the Union; its main purpose was to expose to statisticians some of the more exciting current research conducted by demographers. Three papers were presented and a discussion of each was lead by Germán Rodriguez. Juha Alho presented a paper modelling the effect of demographic and economic uncertainty on fiscal sustainability. Initially stable population analysis was expanded to include the effect of stochastic economic productivity. Diverse demographic trends in Europe were then used to illustrate the difficulties in achieving accurate population forecasts. Contrary to conventional wisdom, it was shown that, in forecasting fiscal sustainability, demographic uncertainty is approximately as important as uncertain economic trends. Jan Hoem's paper applied an extension of piecewise-constant hazard regression to analyse jointly the transition to cohabitation or marriage using data from the Russian Federation and three eastern European countries. Large inter-country variations in the rise of cohabitation were apparent and the implications for the concept of the ''second demographic transition'' were discussed. In the final paper John McDonald showed how a Bayesian modelling framework could be used to generate estimates of place-to-place migration flows with associated measures of precision. The advantage of this approach includes its ability to deal with reported flows of varying quality and with missing data.

Global Science Panel on Population and Environment
The goal of the IUSSP Global Science Panel on Population and Environment is to prepare a scientific state-of-the-art assessment about the role and incorporation of the population focus in sustainable development and to build a substantive bridge between the Rio and Cairo processes. The Panel, organised by IUSSP, the International Institute for Applied Systems Analysis (IIASA), and the United Nations University (UNU), is under the joint patronage of Maurice Strong and Nafis Sadik and consists of 20-25 distinguished scientists from different relevant disciplines. The Panel's mode of operation will follow the example of a uS-NAS Panel with the following differences: It will have a truly international basis, will be interdisciplinary, and aims at producing direct substantive input to the Johannesburg 2002 summit.
