In 2006, the town of Wormer had 12566 inhabitants. The built-up area of the town is 16.88 km² (of which water: 4.19 km²).
Wormer, together with Engewormer (Wormer c.a.), was a separate municipality until 1991, when it became a part of the new municipality of Wormerland.
The inhabitants of Wormer repulsed several attacks of the Frisians and West Frisians in 1280. Floris V, Count of Holland rewarded this with an exemption from paying toll in Holland, an important privilege at that time. Important skirmishes between Spanish troops and the Geuzen took place in Wormer during the Eighty Years' War. At Whitsunday (Pentecost) 30 May 1574, 1400 Spanish soldiers tried to capture Wormer and Jisp. They were crushingly defeated by a combined force of locals, Geuzen and filibusters, bringing an end to the Spanish tyranny in the Waterland area. In the following century Wormer became very prosperous from the production of beschuit (rusk). At least 130 bakeries in the town were once supplying the countless ships of the Dutch East India Company. Other important industrial activities in the town during this period were the production of starch and the processing of whale blubber. At least 66 windmills were once built in Wormer, but nowadays only one windmill (de Koker) has been preserved.
