Between 2012 and 2013 the population of Latvia fell by 22 400 to 2 001 500, mainly because of emigration. Official statistics from Statistics Latvia indicated that outflows (22 600 in 2013) exceeded inflows (8 300), resulting in a net outflow of 14 300 in 2013. Ethnic Latvians accounted for 37% of total inflows and almost half of total outflows. The non-Latvian population numbered 304 800 at the beginning of 2014, equivalent to 15% of the total population. Non-citizens of Latvia, mainly longstanding residents from other parts of the Soviet Union, comprised 83% of the non-Latvian and 13% of the total population (253 600 in 2013). Their numbers have decreased from 730 000 in 1995 due to both emigration and increased naturalisation. Russian nationals were the second largest group of non-Latvian residents (38 800 in 2013).
