How can I get access to all monthly data (months from january to december) for the period 2010-2014?
The IPUMS-CPS team is currently working on integrating the CPS basic monthly datasets from 1976 to present. There is no official expected release date for these files at this time. All of the basic monthly files from 2010 to 2014 are currently available from the Census Bureau FTP page. These files will include most of the variables you have listed, however they will be listed under different variable names as these files are created by the Census Bureau.
The variables NCHILD and NCHLT5 are created by IPUMS-CPS so there is no equivalent within the Census Bureau files. These variables use the family pointer variables MOMLOC and POPLOC. Within a household, each person’s PERNUM is compared to the values of MOMLOC and POPLOC (which gives the PERNUM of a respondents mother or father) of every other household member. If a person’s PERNUM matches the MOMLOC or POPLOC of another household member, that other household member is counted as a child of the original person and the original person’s NCHILD value is increased by 1. Using the logic described on the family interrelationship page along with this description you may try to construct NCHILD and NCHLT5 using the Census Bureau CPS basic monthly files.
I hope this helps.
