In the past twenty years, the number of working persons with tertiary education has grown fast in the regions of the Czech Republic. At the same time, the number of working persons with primary education as well as the number of working persons with secondary education without graduation certficate (maturita) virtually in every region have significantly dropped. However, employment structures by formal educational attainment differ markedly from region to region, the Czech Statistical Office says. 

The total number of working persons aged 25 - 64 years with tertiary education reached 1,113 thousand persons in 2015 and their number has grown by 613 thousand persons since 1995. This increase is much higher than the increase in total employment in the national economy over the period observed.
