Demographic data for Slovenia for the last 90 years indicate that the diversity of mother tongues is now larger than before, eventhough the share of resident with Slovene as their mother tongues has been decreasing since 1953. Since 2002, when according to Census population there were more than 40 mother tongues, every year between 10,000 and 30,000 people (in 2008 and 2009) immigrated to Slovenia, most of them (almost half) from the area of former Yugoslavia. However, immigrants came from almost 30 countries.
