Good morning,

 

I’m new to the listserv, but I’m working with CTPP data and had a question where I think I need outside experts with more experience in the dataset. I am working with a CTPP dataset (covering Miami-Dade, Broward, and Palm Beach Counties) and have been asked to find the sample sizes that were used for the estimates.

 

Are the sample size numbers publicly available? If so, would you point me in the right direction?

If they are not available, are there any methods you could suggest to find (with all necessary cautions) the sample size given the estimate and margin of error data that is available?

 

Please let me know if I need to amend the request,
