I have had a great experience with Nacda-the national archive of computerized data on aging at icpsr. The customer service was excellent and the website is very user-friendly. I would highly recommend them to anyone looking for aging data. The information provided is thorough and reliable, making it a valuable resource for researchers and professionals.
