Population of generations in the United Kingdom (UK) 2015 In 2015, there were over 14.8 million baby boomers in the United Kingdom, making it the largest generational cohort at that time. The millennial generation, or Generation Y, accounted for 13,8 million people, while there were 13 million members of Generation X.
Post-war baby boom
The baby boomer generation is the largest due to the spike in births that happened after the Second World War. In 1947 for example, there were over 1 million births in the United Kingdom, compared with just 657 thousand thirty years later in 1977.
