nsch stands out as the best way to answer research questions on state-level children's health care and the family environment, especially for younger tykes who are often an afterthought in other survey data sets. the youth risk behavior surveillance system (yrbss) only interviews teenagers, the national longitudinal study of adolescent health (addhealth) follows kids for long periods of time but doesn't follow nearly as many of them, and while the national health interview survey (nhis) includes a sample child component, it cannot be used for state-level estimates. before you sink your teeth in this data set, you must read the frequently asked questions document. eight pdf pages of bliss.
just so you know, emily rowe at the university of chicago's data science for social good co-authored this blog post and all the r scripts in between. emily contacted me out of the blue to offer up some nsch code she had written for an impact evaluation of the nurse-family partnership, and i convinced her to spend a few more days polishing up her work for public consumption. so here you have it. this new github repository contains three scripts:
download and import.R
- download the microdata years you've requested
- unzip the microdata files you've requested, alongside multiply-imputed poverty
- merge to construct a fantastic five implicates
- save the r data files to your local disk
- load and slim down the five implicates to only the variables you need right about now
- construct a taylor-series linearized complex sample survey design object with multiply-imputed poverty
- recode a few variables just so you can do the same when you leave the nest
- perform five, ten, a million different analysis examples so you know how to do most anything
- load and slim down the same five implicates
- construct the same taylor-series linearized complex sample survey design object with the same multiply-imputed poverty
- match statistics, standard errors, confidence intervals displayed by child health data dot org
- for statistics broken out by poverty, run the analysis the more rigorous (ie. the right) way

- the child health data dot org online table creator
- the cdc's nsch homepage, as part of the state and local area integrated telephone survey, a better source of information than..
- the health services and resources administration's maternal and child health home, which does not yet have the latest survey results posted
the main portal to all things nsch is actually run by the oregon health and science university's child and adolescent health measurement initiative. they have tens of hundreds of statistics and data briefs, articles, presentations, etc, etc, etc. that you owe it to yourself to review before you embark on your own analysis.
