In Greenwich the number of children born is consistently higher than the number of residents who are dying; in 2019 there were 4,125 live births and 1,563 deaths. This gives rise to a natural increase in the population with more births than death. However, while this gives an estimate of the crude rate of increase, this does not take into account people moving into or out of Greenwich.

Over the last five years the rate of natural increase  has decreased slightly,  with fewer births and fairly constant death rate.

The demographics of mothers in Greenwich are changing; women are in general older now when they are starting their families than in previous years and are from more diverse backgrounds with a growing proportion of births to non-British born mothers. 

In 1997 the average age of women giving birth in Greenwich was 27.9 years, by 2016 this had increased to 31.1 years.

The proportion of non-British born mothers has risen by 32% between 2001 and 2011 with the percentage with the majority of non-British born mothers born in Europe (30% or 1,375 births).

Migration

Understanding the impact of Migration is more complex as there is no legal requirement to inform any organisation when someone moves in or out of an area or country. As such, data on migration (internally within the country and externally from other countries) is much less robust and comes with limitations on its use. One source of information we have is through the issue of National Insurance Numbers (for work purposes) but this won't be the complete picture of migration.

Economic migrant data from the Department of Work and Pensions reports there were 5,392 National Insurance Numbers registered to overseas nationals (April 2017 to March 2018). Two out of three National Insurance Numbers registered were for people from the European Union.
