the proposed system provide better pay-out than in the existing pay-as-you go system; can the proposed system
avoid old-age poverty; can the retirees maintain pre-retirement standard of living? This presentation uses a
simulation with present value approach to find the answers. The conclusion is that the retirees may need to find
other sources, not only depending on retirement pay-out, to create their old-age financial adequacy. It provides
some lessons for other similar countries.

1796 Digitalization, Big Data, and Demography

Francesco Billari

Abstract

Technological change has shaped demographic behaviour throughout history. The digital revolution, or simply put
digitalization, i.e. the diffusion of the Internet and of wireless communication technologies is no exception. On the
one hand, ‘digital footprints’ provide new sources of big demographic data, opening novel research avenues and
methodological challenges. On the other hand, the digital revolution is shaping demographic behaviors, and we
will provide an outline of findings on the impact of digitalization. This novel field has exciting and big challenges
for population scholars.

1797 Demographic Trends in Southeast Asia: What Lies Ahead?

Charles Hirschman

Abstract

Southeast Asian population forecasts for the 21st century are used to illustrate the progress and limitations of

on Bayesian hierarchical modeling, demography has made significant progress. However, demographers have
frequently been surprised by unexpected population trends over the last century. In addition to a reliance on high
quality data and statistical models, humility is an indispensable asset of demography.
