Latest update: 17 July 2022 (Sun) | 2021 | 2020 | 2019 | 2018 | 2017 | 2016 | 2015 | 2014

1. Overview

Demography is one of the essential methodology to grasp the characteristics of human population survival. It can support the understanding of epidemiology and public health. This lecture basically use a textbook for basic formal demography and demographic models, followed by several examples of actual demographic researches.

Using computer practices may be helpful for understanding. Bringing your own laptop computer is recommended. Software to be used is GNU R, which is free software (

2. Plan

The lecture is done in first semester on Thursday, 13:10-14:40 via Internet. Please check BEEF.
