Hmm… This is strange. I just downloaded your extract #4 on my computer and opened it in Stata with no problems. The data is loaded in as expected. I suggest watching the video tutorial we have about downloading and opening IPUMS data in Stata. This may help uncover the issue. If the issue persists, feel free to follow up with an email to ipums@umn.edu and we can try to help troubleshoot the issue.
