Yes according to your bar graph there tends to be a increased age gap between couples in the UK, but not on the same magnitude as it is with age gaps of 25 years plus (your bar graph only goes up to 10 years) with Philippine-foreign couples. I rarely see a guy my own age from the UK in Manila. As soon as Filipinos see my wife with my daughter they instantly think that she has married a old guy. I think per person ratio you will find that age gaps will surely be highier with Brit-Phil than it were with Brit-Brit!
