Whenever I do searches, the first links for me are from the CDC, and I haven't checked much to find UK data. But I know death rates are lower in the UK than in the US, mainly because the US mishandled the outbreak so badly. I was very surprised when you mentioned so few deaths in your age group, but I assume you were talking about deaths in the UK, because the number you mentioned (around 137 if I recall correctly) doesn't match well with US numbers (but US also has a much higher population, of course). Here is recent data for US:
