Subject SES
***********


Overview
========

Kristi and Meredith have compiled a table of basic demographic/SES info for all
our Project 2 subjects.

.. warning::

    This information is based on information collected during a subject's 
    first home visit at 14 months of age. Note that some of the variables 
    are susceptible to change (PCG, income, education, etc.) at later 
    timepoints.

The :download:`Project 2 SES data file <ses.zip>` is in TSV (tab-separated value) format. Column descriptions are given below. 


To Do
=====

This summary table could be extended to include change status variables 
for each variable susceptible of changing. For example, paired with the 
*pcg* column would be a *pcg_change* column, simply indicating whether the 
PCG value indicated changed at a later timepoint.
