Hello! I am curious about whether it is possible to access the namefrst and namelast variables for the full count 1910-30 censuses. This is for academic research purposes. The IPMUS USA website states that we should apply for access at the North Atlantic Population Project (NAPP) at IPMUS USA. I applied and was approved. However, on the IPMUS USA website, I see that access to full-count censuses ends at 1910. Are subsequent censuses (1920 and 1930, 100% samples) with namefrst and namelast available for research use?
