Between 2015 and 2016, Swansea's population increased by approx. 2,100 (+0.9%).  This is higher than the average increase across Wales (+0.5%) and the third highest annual growth rate (%) of Wales' 22 authorities - Cardiff and Newport being the highest (+1.0%).  Analysis of the supporting data released with the population estimates suggests that Swansea's population growth during the year to June 2016 was driven by net international in-migration (+1,860); and to a lesser extent internal (within UK) migration (+350); with natural change (births minus deaths) essentially unchanged.
