 Although according to Polish Election Committee in fact the number of Poles was much higher, about 10% of total population, this number was based on election results.Many Poles in Lithuania were signed in as Lithuanians in their passports, and as a result, they also were forced to attend Lithuanian schools.While the number of Polish language schools in Lithuania increased from 20 to 30 from 1920 to 1923, and to 78 in 1926, they decreased to 9 by 1940.
