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.

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
