How might old-age dependency change in the UK over the next three decades?

Yesterday, I presented charts indicating how old-age dependency is projected to increase in the US over the next three decades. Today, I present similar charts for the UK. Data are from the Office for National Statistics.

The first chart shows the projected percentage increases in three different segments of the UK population up to 2035: those of working age (15-64), the elderly (65+), and the very elderly (85+). The second chart shows how the elderly dependency ratio is projected to increase over this time period, while the third one shows how the very-elderly dependency ratio is projected to increase. The percentage increase in the projected elderly dependency ratio is ~50%; the percentage increase in the projected very-elderly dependency ratio is ~130%.
