Greystones has experienced a huge increase in its population since the 1970s with the construction of mainly large housing estates. The first of these periods lasted for around a decade seeing the development of estates like Hillside, Applewood Heights, Redford Park and many other smaller ones like Burnaby Park. The second boom in construction came during the Celtic Tiger period of the early 2000s which saw developments such as Charlesland (the biggest) just south of the town, which includes over 1,000 dwelling units. Following the 2008 Financial Crisis little development took place, evident in the difference from the 2011 to 2016 census'; an increase of only 1000. This is compared to previous increases like 2006 showing 3000-4000 in growth. Other projects such as the harbour redevelopment stalled or completely halted during this time period.
