Overview of NCHS Data Access Tools
Tool Ease Level AvailableDATAFERRETT 15 Datasets, including
NAMCS, NHAMCS, NHANES, Mortality
(UCOD), NHIS
ICSPR Many datasets, including most NCHS surveys (Vital Stats
available in ASCII only)SETS Selected NCHS sets:
Over 80 Available!
Data are released from NHIS and others In ASCII (raw data files—you need your own statistical package to use, like SAS, SPSS, or STATA) On the Internet, as an Early Release In publications, such as Health, United States
Using Health Insurance Data: Non-Tools
Early Release of Selected Estimates Based on Data From the January-
March 2006 National Health Interview Survey
From: http://www.cdc.gov/nchs/about/major/nhis/released200609.htm
Health Insurance Coverage: NHIS data in Health, U.S.
From: http://www.cdc.gov/nchs/hus.htm
Using NCHS Data Tools to Find
Data on Health InsuranceTo find data on health insurance, we will look at 3 tools:Health Data for All AgesSLAITS data from the CAMHI Data Resource CenterData2010 (Healthy People 2010 Objectives)
Please Note: You can also find health insurance data from Trends in Health and Aging, SETS, DataFerrett and ICPSR
HDAA has health insurance tables (pretabulated data)
In this pretabulated table, NHIS data years are combined to make the statistics more reliable and
more useful for breakdowns by age, sex, race/ethnicity and geography.
The view is now the percentage (with upper and lower bound confidence intervals and standard
error) of uninsured children (ages 0-17) by sex.

Charting and Exporting the Customized Data
An online query system, with national and State data available
Creating a table with %, CI, n, and a weighted estimate (you can also compare one subgroup at a time)
Creating a chart (with presentation selections)
DATA2010:
Another query
system--very similar to
WONDER and WISQARS
most recent data for
Healthy People 2010
467 objectives
National and state data (if available)
All of the outputs contain a baseline, target and available data
Finding Data on C-Sections: Non-Tools
Data are released from Natality Branch (Birth Certificate Data)
In ASCII (raw data files—you need your own statistical package to use, like SAS, SPSS, or STATA) On the Internet, such as a FASTSTAT In publications, such as Health, United States, etc.
Using NCHS Data Tools to Find Data on C-Sections
To find data on c-sections, we will look at 3 tools:the Office on Women’s Health (Quick Health Data Online) toolthe VitalStats site (this site is note live yet, but wanted to give you all a preview of it…)the Statistical Export and Tabulation System (SETS)—the only tool not available online yet
An online query
system. Find
data by topics (11), some State
data is available
.
Another site with tables,
ready for custom-
ization. This site also has data files and mapping. State and national data are
available.
VitalStats: A Site Not Yet Available, but Coming Soon!
Here, I created a table from a data file. I used a c-
section variable, a race recode and
state of residence.
Again, please note these data are not
live…this is a DRAFT site!
Using VitalStat
s data files and tables
Mapping on VitalStats
Again, please note these
data are not live…this is a DRAFT site!
Mapping on VitalStats (zoom)
I changed the view to look at only “primary” c-sections and then panned an zoomed the view and
highlighted the lovely state of Massachusetts.
When you use SETS, one of the database systems, you have
full access to the
complete data set.
You can even also browse the data record by record or variable by variable.
Using SETS to Access C-Section Data
Using SETS to Access C-Section Data
Using SETS to search for Suffolk County
Using SETS to create Primary C-Section Table for Suffolk County,
MA
Using SETS to Create a Cesarean Delivery Table- Recodes
You can recode the variables in the data set for your needs. For instance, if you wanted to look at a different age group than what’s provided on the data file, you could recode age groups. I combined two groups for two new categories of
age: “Under age 20 years” and “40-49 years.”
You can also chart and export your data
DataFerrett: A Tool from the Census Bureau
Interactive Data Tables
Advantages: Pretabulated, don’t have to
worry about misusing data—all concerns are addressed!
Lots of data from many data sources, organized by topics
Nice presentation capabilities (VitalStats will have mapping)
Not as fast as online queries, but still fairly fast
Disadvantages: May not
contain the data needed
Can only use options already in table (or data file, on VitalStats)
A little learning curve
Simple Queries
Advantages:Fast, easy and
online!Lots of data from
many data sources, organized by topics
Lots of data available
Disadvantages:May not
contain the data needed
Can only use options available
Generally descriptive
Complex Queries
Advantages: Complete access to
data set (in SETS—also documentation)
More flexibility with the data
Encourages greater understanding
Good searching capabilities
Access to other data sources
Disadvantages: Some learning curve SETS and FERRETT
require downloads and ICPSR requires log in
May not have all the analytic capabilities for complete analysis (export) but better than the other tools
May require more knowledge about the data
