What do demographers do?

Demographers study populations to determine their size and composition and to predict how they are likely to change in years to come. In all countries, this knowledge is key to meeting the population’s present and future needs, for example, to decide how many new kindergartens, schools or retirement homes are needed. Demographers analyse data collected by the national statistical offices (INSEE in France) and organize surveys on specific themes. To become a demographer you need a Master’s degree in demography or a related discipline, such as sociology, statistics, geography, biology etc. You can also study for a PhD to specialize in research or to teach demography at university level.
