IPUMS NAPPs samples US 1850b 1860 and 1870 show value zero for variables nchild, nchlt and nchlt5 for females

As stated in the title. The counts are given for males (sex==1), but for females the value is always zero. This is problematic, because I want to count the number of own children a women has, independent of marital status. For latter census (1880 onwards) it is fine. Thank you.

Thank you for pointing this out to us. These variables have been updated and the fix is now live on IPUMS NAPP.
