Pensioners in west London will have far less sway in the General Election compared to those in the rest of the country.
Just 11.9% of the area's 237,681 population are aged 65 and above, placing a relatively small amount of influence in the hands of these older voters.
Although this influence is likely to be slightly higher because pensioners are some of the most likely people to actually cast a vote on election day.
Within west London, the constituency of Hammersmith has the smallest proportion of pensioners with just 9.4% aged 65 and above.
Ruislip, Northwood and Pinner have the largest proportion of pensioners at 19.8%.
Throughout the whole of the UK, 17.4% of the population is aged 65 and above while the figure is slightly higher in Wales at 19.5%, according to the Office for National Statistics.
