Of these, 25 were men, 22 were women and eight were children. The most represented age group was 25 to 29 years old.
"Nowadays the main cause of international emigration is the economy: since 2009, more than 200,000 people have left Latvia because of the economic crisis," the memo says.
The statistical average of the persons who left was an unmarried Latgalian man aged 25 to 29, with at least middle school education.
The proportion of ethnic Latvians who leave is shrinking, and consequently more minorities choose to leave. Latgale has the highest human drain in absolute numbers but proportionally more people are leaving the Kurzeme cultural region.
Half of the people who leave are not married, while of those who leave at the age of 40 to 65 the divorcee proportion is twice the national average.
People who leave have received less formal education than those who don't. Each fifth of them had higher education, and half of them had finished middle school. This means they may have had trouble finding well-paid jobs in Latvia.
