Tips
Key Points to Keep in Mind:
• What is the original source and how reliable is it?
• How old is the data?
• How was the data gathered and analyzed?
• How complete is the data?
• What are the pros and cons for a specific dataset?
• Understand sample size, margins of error, confidence interval

21. Aggregation
ZIP Codes Yuba County
Yes, because…
The data values are raw numbers such as number of housing units
or population
Can you aggregate the number of births by ZIP Code to find out
the total number of births in Yuba County?
?
22. Aggregation
ZIP Codes Yuba County
No, because…
The data values are percentages or rates, such as percentage of
families in poverty or drop out rate
X?
Can you aggregate the birth rates by ZIP Code to find out the
birth rate in Yuba County?

27. Data Visualizations
Pie charts are useful for showing significant
differences in percentages as parts of a whole.
*Remember—values need to add up to 100%
Bar graphs are useful for
comparing data between different
groups or showing changes over
time.
Line graphs are useful for
showing changes over time.
30. • Help reveal larger place-based
dynamics that numbers by
themselves cannot
• Connect community knowledge and data to location
• Support strategy through communicating patterns to a
broad audience, clearly, quickly, and dramatically
Why Are Maps Useful
Visualizations?
31. Organizations can use maps to:
• Act on an issue/Confirm action
• Strategy: Community Organizing
• Strategy: Advocacy
• Highlight an issue or a specific
aspect of an issue
• Strategy: Media/Communications
• Strategy: Policy
• Strategy: Grantwriting

Mention that most of the data seen on our site is quantitative in nature, counts of people that fall into a certain category. The qualitative piece often comes in from attitudes of residents, that you can gather using short or in-depth interviews of residents in your community, etc. Qualitative data describes whereas quantitative data defines/measures. Ex: An interview of community residents’ attitudes on police presence in their neighborhood. Quantitative Ex: The count of people without health insurance in Los Angeles County.

We have data from a wide variety of sources such as the US Census, CA Health Interview Survey, CA Dept of Ed and more. We also have User Uploaded data which is clearly labeled as such on HC.org and which we do not verify or vet. Here are some tips for vetting data sources you encounter.
Relate back to HC.org. Is it reliable? Would the same survey produce the same results again? This is related to consistency and stability of the data collection method.Is it valid? How well does it measure what it says it measures?

Variables: Ages 0-5, Percentage AdvancedIndicators: Age, 3rd Grade English-Language Arts LevelsSuppose you only have data, such as population, by county. Can you “aggregate” the data and come up with a population value for a larger geography like state?

Data values with margins of error, which includes all ACS data are also non-aggregatable. Example: ACS 2005-09 5-Year Veterans Population for Yuba City is 4,938 (4,580 ~ 5,296).That means that the true value is somewhere between 4,580 and 5,296.
Indicator: Gen. CharacteristicVariable: Specific CharacteristicData Levels: Although your community or place may be identified by specific street boundaries, geographies are spatial (non-physical) boundaries, such as census tracts or ZIP codes. Administrative data, or data collected by persons, organizations or departments of government for their own purposes but often made available for public use, is usually collected for these geographies. To use this type of data in your research, particularly for making comparisons over time using multiple years of data, you will need to determine which geographies represent your community or place.Universe: Population/people included in the datasetMetadata is data about data! Source, year, methodology, geographical coverage, description of indicator/variables, data levels available.

Why use visuals? Gives people perspective provides context helps people relateThese are some things we’ve found helpful about visuals. Anything you want to add that would be key for a visual?
-Ex. 36% of all people prefer apple pie.-Ex. People buy more oranges compared to mangos. Do not have to add up to 100%. May also show change in number of apples bought over time.-Ex. population change growth over time comparing males and females.

Thematic – data aggregated to political, jurisdictional, or other boundaries such as counties and ZIP Codes. For example the number of families in poverty or the number of unemployed civilians in a city are displayed as thematic layers on our maps.Thematic/Indicator dataDemographic (population, educational attainment, ethnicity, etc.)Civic ParticipationChild WelfareChild Care & Early EducationIncome & PovertyEmploymentNonprofit InfrastructureEnvironment & Land UseHealth – Birth, Prenatal & ChildHealth - Conditions, Disease & InjuryHealth – DeathsHealth - Insurance & accessHealth – Physical Activity & NutritionNeighborhood & CommunityCrime & Public SafetyHousing
Viewing point and thematic data together enables you to get an initial picture of the distribution of resources, while understanding a particular characteristic about an area. For example, are there educational resources in areas with low educational attainment? Is there access to fresh food in areas with a high concentration of people with diabetes?Point DataGrocery StoresAlcohol OutletsNonprofit OrganizationsSchools (Public & Private)WIC Agencies & VendorsHospitals (OSHPD)Head Start AgenciesChild Care CentersEPA Hazard SitesFed.

Check CashingCommunity Services (detailed Social Service data from 2-1-1 for 16 counties: Over 30,000 Service sites in CA; includes: Basic Needs, Legal Services, Education, Health Care, Employment, and many other Community Services)
Today we’ll look at two of the functions on HC.org: Maps and Charts. We’ll start with maps.You can access thematic data in the Map Room either by clicking on the Maps link at the top of the page or by using one of the quick links in the middle of the page which let you skip a few steps if you already know what you want to do.
We now see a map of HS grads in the city of Riverside. In this box you will see the name of the indicator you chose along with its metadata such as description, universe, source, year. As well as the data level, which is the geography at which the data is displayed. In this case it is Census Tract but if you were mapping the whole state of CA, you may want to look at a different data level such as County. HC.org automatically chooses a data level for you based on the geography you choose. However, you can always change it here if you want to see more/less detail (as long as data is available at multiple levels).Second, you’ll notice the legend in the bottom right corner, this shows you the range of values for the whole dataset, the indicator/variable name and the data level.Finally, you can view 2 thematic datasets at a time on HC.org, so you could click another Target and add a second characteristic like Percent of Families in Poverty or Median Household Income.

You can change the color scheme and the data ranges among other things.
Quantile: Each class contains an equal number of features. Equal Interval: Divides the range of values into equal-sized sub-ranges.Percent of African-Americans in California = 5.8%…Use Quantile to see where the highest concentrations of small populations areIn areas with higher Percent of African-Americans like south Los Angeles,…Use Equal Interval to see variation in areas with highly concentrated populations
You can access the Data Room using these links
In this example we are looking at a table and chart of Births by Mother’s Age in Fresno County. We get the information in table and chart form.
You can compare many geographies in the Data Room. You can also compare geographies in the Map Room but it is limited to two at a time. You can use this drop-down menu to change which year of data you are viewing (if >1 is available). In addition, you can view all years of data available at once, allowing you to trend data over time (data permitting). Finally, you can also change the type of chart from Bar to Pie to Stacked. Remember, pieces of the pie chart must add up to 100%!
Here’s where you’ll find the metadata in the Data Room. Whenever you see a red number next to your geography, that means the data is aggregated. It is a good idea to note which data level is being used for the aggregation. At this time you are not able to change the data level in the Data Room, although you can in the Map Room.
