My name is Susan (born 1951) and I was named after my grandmother who was born in the early 1900's which would have been rare back then. I live in New Zealand and am surrounded by Susan's or Sue's. I was always called Susan growing up, but have been called Sue since my late teens. The name Susan was really popular back in the 1950's in NZ and I hope one day that the name Susan has a revival. I'm proud of my name... I love it!

Most people I've met or heard of with this name are grownups. Susan is not popular anymore, and it is most often given as an independent name. It is more popular than the original form Susanna. Susan still is on the Top 1000 names for girls, but it is much less popular as it once was back then. Sue and Susie are common nicknames.
