More time is fine. Thank you.
OK. No problem.
Hello, Thank you for using this service. I wish to introduce myself. I am a Research Librarian with 20+ years of experience.
Attached is a link from the US Census Bureau that for 2011 has information on households with the age group you are looking for. Only thing is that not exactly sure if the age group is related to each other.
Look at Table H2
I hope that this can be a start in getting an answer to your question.
Oh, not even close. What you gave me is a cut at households, which has nothing to do with my question. So let me state it in another way.
I am 68. I have three older siblings. We have no deceased siblings. So, we have been four siblings for 68 years. I believe that to be quite rare! Is it? I.e., out of the entire population of the USA, how many people belong to four-sibling sets that have been endured for at least 68 years?
The information I am looking for may not exist. Not too many people are likely remotely interested in my question.
You're welcome. Thank you for the information. Pretty close, and gives me a good handle on what I'm looking for: we are pretty lucky to have started with four siblings and 68 years later still have four siblings.
