A word derived from the ancient Greek, “demography” literally means “describing the population”. And that’s precisely what demographers do: they describe the size, composition and structure of populations. The term “demographic change” is most commonly used to refer to shifts in population structure that have emerged in many industrialised nations including Germany since the 1970s, chiefly as a result of three major developments: declining birth rates, longer life expectancy and increasing immigration. These changes present many challenges, but many opportunities, as well.
