I saw 65 years old or older used by reliable sources such as the New York Times. Does "old" and "older" sound repetitive, or is it just the way to say it? Would it be better to use "65 years old or higher" or "65 years old or greater"?

Also, for this graph, should I use "65 years old or older" or "65 years old and older"?

1n 1940 approximately 7% of Sweden’s population was 65 years old or/and older/higher/greater.
