Asia-Pacific Population Journal

For over two decades, the Asia-Pacific Population Journal (APPJ) has been taking the pulse of population and social issues unfolding in the region. Published by the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP), APPJ brings out high quality, evidence-based and forward-looking articles relevant for population policies and programmes in Asia and the Pacific. Prominent population experts, award-winning demographers, as well as lesser known researchers have been contributing articles, documenting over the years the evolution of thinking in this important sphere.


Longitudinal research designs and utility in the Asian and Pacific region

Longitudinal research, which includes panel research, is the term used to differentiate the methodology and utility of prospective studies from that of cross-sectional research. It describes not a single method, but a family of methods that measure change by linking individual data across time (Zazzo, 1967, cited in Menard, 2002).
