According to the figures provided to BNS, 4,181 people declared emigration in May, which is a decrease by 462 individuals month-on-month.
The incoming numbers also increased, with 2,124 people immigrating in Lithuania in May, up from 1,770 in the earlier month.
The emigration figures went down after a major increase at the beginning of 2017 when about 7,000 declared emigration.
Some experts say the increase in emigration numbers was temporary due to emigration declarations filed in early 2017 by those who had left earlier to avoid the duty of paying mandatory health insurance, while others could have rushed to Great Britain before the start of its Brexit talks.
Lithuania last year lost around 30,000 people due to emigration to Western Europe. Opinion polls show that the majority of emigrants leave Lithuania for Western Europe in search of higher pay, while some experts say emigration may be fueled by major inequality of income.
The Lithuanian population shrank from 3.7 million in 1990 to 2.83 million this year due to aging and emigration.
