Chapter 2 discussed how the workforce involved in the construction and operation of any major project is likely to be drawn partly from local sources (within daily commuting distance of the project site) and partly from further afield. Those employees recruited from beyond daily commuting distance can be expected to move into the locality, either temporarily during construction or permanently during operation. Some of these employees will bring families into the area. In-migrant employees and their families will exert a number of impacts on their host localities:

• They will result in an increase in the population of the area and possibly in changes to the age and gender profile of the local population.
