By 1920, the population was 47,946; by 1925 it was 63,870 and in 1935 that had ballooned to 103,030. The explosive growth of industry in the region and the subsequent housing needs of workers called for radical changes in administration, as the City of Eindhoven was still confined to its medieval moat city limits. In 1920, the five neighbouring municipalities of Woensel (to the north), Tongelre (northeast and east), Stratum (southeast), Gestel en Blaarthem (southwest) and Strijp (west), which already bore the brunt of the housing needs and related problems, were incorporated into the new Groot-Eindhoven ("Greater Eindhoven") municipality. The prefix "Groot-" was later dropped.
