Although the majority of the population remained bilingual until the second half of the 20th century,[13][2] the original Brabantian dialect[26] was often no longer passed on from one generation to another,[27] leading to an increase of monolingual French-speakers from 1910 onwards.[21][28] This language shift weakened after the 1960s,[13][29] as the language border was fixed, the status of Dutch as an official language was confirmed,[30] and the economic center of gravity shifted northward to Flanders.[9][10]
