Long-term principal assumptions in England 2014-based population projections Fertility: Average number of children per woman: 1.90 Life expectancy: Expectancy of life at birth in 2039 Male: 84.4 Female 87.2 Long term annual net migration: +170,500

So those arguing Brexit means to have to lower OAN estimates in local plans – make everyones lives easier by improving the statistics by getting out of the country.
