“…Examples of sophisticated spatial demographic work in SE Asia are numerous; too numerous to be adequately presented in a short comment. Included in this body of literature are research programs that were and continue to be cutting edge, including: detailed studies of the interactions between population settlements and environment (Walsh et al, 2005, Kermel-Torrès, 2020, Schönweger, 2012, sophisticated analyses of migration movements and settlements (Shao et al, 2008), novel approaches to measuring access to family planning services (Entwisle et al, 1997, Rittirong et al, 2013, detailed work on changing fertility patterns in places where data are scarce (Schuster et al, 2019), and the generation of gridded population estimates across the region (Gaughan et al, 2013. ) This list is not exhaustive, but rather is meant to illustrate the wealth of spatial demographic work that has been done in this region.…”
