The Office for National Statistics (ONS) produces estimates of the resident population in the borough each year. They do this by calculating the number of births and deaths in the borough and by estimating the impact of internal and international migration. ONS also produces population projections to estimate what is likely to happen to the population in the future.

Mid-year population estimates

The mid-year estimate for 2014 was released by ONS in September 2015. This estimated Merton's population at 203,515. The table below shows the mid year estimate for every year since 2001. Please note that this series was reassessed in 2013 using new data from the 2011 Census and all the figures were revised.

Population projections

ONS also provide population projections for each borough that estimate future changes. In May 2014 a new series was released that used the 2011 Census findings. Historically these projections have significantly overestimated the growth in Merton and at each Census have been revised downwards. For example prior to the 2011 Census the projected population for 2020 was 239,600 and this has had to be revised down to 223,900.

Year Total residential population projection
2015 210,300
2016 213,200
2017 215,900
2018 218,700
2019 221,300
2020 223,900
2025 235,700
2030 245,700
2035 255,000

Greater London Authority Population Projections

The Greater London Authority (GLA) provides a range of demographic data and maps through their London Data store. They have also attempted to predict what will happen to Merton's population but have used a different method to ONS including likely levels of development. The GLA figures generally show a much slower rate of growth and in the past have better reflected the findings from the Census.

Year Total Resident population projection
2011 201,226
2012 202,887
2013 203,878
2014 205,573
2015 205,648
2020 205,988
2025 206,387
2030 205,022
2035 203,991
