I have been trying to download ZCTA-level population from B01003 since yesterday but it goes into an endless loop until finally suggesting to end the script. I have been successful with several other detailed tables - could it be that this is the most popular? Is there an FTP or other way to get this data set? Regards, Rex

Hi Rex. What tool are you using? (data.census.gov or the API?)
There is a way to download and extract all of the Summary Files (using FTP) if you have SAS or similar statistical or database program available to you. (Here's the Summary File handbook if you're interested: www.census.gov/.../summary-file.html)
