“The proportion of people aged 65 and over increased by 47% between 1974 and 2014, while the number of elderly people represents almost 18% of the population total in 2014 in the United Kingdom. » (ONS, 2015), this means that population aging could change the age structure of the UK population and the number of retirees could increase. For this reason, the demand for labor could also increase. The labor shortage could make it difficult for the government to support funding for aged care, such as pensions, health care and social services. Additionally, Christensen et al. (2009) considers that there are few young people to accompany the rapid growth of older people due to the increase in lifespan.
