Workshop Objectives
Locate and obtain data on child health and school readiness from national surveillance systems
Explain some limitations of local level data and how these limitations can affect conclusions
Describe ways in which outcomes for cities and counties differ from each other and from state / national outcomes
Provide hands-on opportunity to work with surveillance data
2
Introduction & Overview
Importance of local data
Introduction to local data sources
What’s available How to use it Advantages and
limitations of these data sources
How city/county level outcomes differ from state/national level outcomes
3
Why is local data important? “. . . . [Such] data are
essential in identifying communities most at risk of poor health outcomes,
exploring the determinants of such variations in health, and
ultimately guiding community health programs and policies.”
From: Shah, Whitman & Silva in “Variations in the Health Conditions of 6 Chicago Community Areas: A Case for Local-Level Data”

Is there local-level information on reading to young children?
Website: http://www.nschdata.org/Content/Default.aspx; accessed 07/26/2011.
15
Data on reading to young children is available on-line at the national, regional, state levels
16
On-line data can be looked at and compared through a number of different subgroups

Why is local-level data so hard to get? Data may not be collected at the
household, city, or county level e.g., some national and state surveys collect
data only for large metropolitan areas, or select a few areas to represent all
Data may be reported only for jurisdictions with populations of 100,000 or more For smaller jurisdictions, data may be
aggregated21
If you do get your hands on local data, what do you need to watch out for? Confidentiality
e.g., “Hey look, this dataset has a family of 12 kids, including 3 sets of twins! I’ll bet that’s the Smiths from down the street. Whoa, it says here that Mrs. Smith only has an 8th grade education.”
Rare events / small numbers of “events” (death, birth defects) limited statistical power several years may need to be combined
22
National, state, or MMSA level data may not capture events at the local level

23
Small populations / rare events in a population can produce dramatic, erratic results
24
Other concerns about data . . . Where did the numbers came from?
a source that collects information on ALL of the population (e.g. Census, Vital Records)
a representative sample of the population a convenience sample of some people
Quality of data is affected by practices related to Recording Collecting Reporting
Potential sources of data differ greatly per type of event – deaths, injuries, illnesses require complex surveillance systems
25
Limitations: How well do county data represent city populations? Some public health issues that affect
cities will not be accurately represented using county-level data Generally, counties are larger
geographical areas that also include suburban and even rural areas
Some large cities are spread over several counties
Some counties do not include their urban central city

YOU can put the pieces together
National vital records and state survey data provide broad context
“Where do we stand?”
Local survey and subpopulation data allow us to dig deeper
“What are underlying causes?”
Local investigation and action
“What do we know about our systems, our communities?”
