1. Data Questions
• High-level data questions
o Who is eligible?
= Poverty Population
o Who requests assistance?
= Intakes
o Who do we help?
= Served
o How do we help?
= Level of Service
o What resources are
required?
= Hours

o Link to detailed questions
 Link to analyses

2. Analysis Types
• Snapshot
o Snapshot analyses measure counts or percentages for a given period, usually the most recently
completed year. If any counts or percentages are unexpected, comparison, trend or spatial analyses
may be necessary to better understand the reasons for the unexpected results.
• Comparison
o Comparison analyses review linkages between two or more variables and uncover information about
client conditions and data relationships. When unexpected data relationships are discovered,
investigation is warranted to better understand linkages and determine whether they indicate the
need for client service and advocacy work that simultaneously targets multiple conditions at once.
• Trend
o Trend analyses scrutinize changes over time in client conditions. Review trends over a five-year
period, or longer when possible. Spikes or dips that appear in trends might confirm what an
organization expects or raise additional questions worthy of investigation to better understand the
unexpected change and determine whether it calls for proactive steps.
• Geographic Distribution
o Geographic Distribution analyses show how people or problems or anything else of interest is
distributed across service areas, which can be divided into smaller areas to reveal spatial patterns.
These patterns are opportunities to learn about the spatial dimensions of your organization and your
clients.
• Geographic Concentration
o Geographic Concentration analyses compare geographic concentrations (high or low) of multiple
variables to determine how the variables and location impact each other.

7. Download the table to Excel.
8. If the numbers downloaded into Excel as text, highlight the relevant cells, right click, and
select Convert to Number.
9. Perform calculations (including adding up all the numbers of people under 200% poverty
(because that is a good proxy for identifying all eligible people) from the various age groups
in the B17024 data).
10. Create a table like the one below in which the results of your calculations can be entered.
11. Create pie charts or other graphics, if helpful.

7. In the “topic or table name” box, enter S1701
and select GO.
8. Download the S1701 table to Excel for your
area for the most recent 5 years. Note that if
your service area includes areas with
populations below 20,000, you should use the
5-year estimates.
• For information about choosing 5-year, 3-
year, or 1-year estimates, click here
9. Enter the numbers of eligible people from
each of the annual S1701 tables into the
columns for each year in the Excel file with the
intake numbers.
10. Create a combination chart in which intakes
are represented by a bar chart and the eligible
population in represented by a line chart on a
secondary axis

Who do we help?
1. Export the total cases closed and served from your CMS to a spreadsheet for the most recently
completed year or the most recent year for which the ACS S1701 table is available.
2. Sort the served cases by county. Review the counties and remove any that aren’t actual county
names or aren’t in your service area. You may have to combine data if counties show up with
multiple spellings.
3. Subtotal all served cases. Then, calculate the percentage of served cases in each county.
4. Open the S1701 table and calculate the total poverty population for the state by adding up the Below
Poverty Level Estimate column for each county. Then calculate the share of the total poverty
population for each county. Add these percentages to a new column in your served cases
spreadsheet.
5. In a new column called Concentration, calculate the location quotient by dividing the served cases %
for each county by the % share of the poverty population and divide that amount by 100. Results
that are below 0.75 indicate that fewer clients were served than would be expected in that county
based on its share of the state’s poverty population. Results that are between 0.75-1.25 indicate that
the expected share of clients were served based on that county’s share of the state’s poverty
population. Results that are above 1.25 indicate that more clients were served than would be
expected in that county based on its share of the state’s poverty population.
6. Create a column called Concentration Ranges in which you enter these categories: “0.01-0.74”,
“0.75-1.25”, “1.25-3.00”, and “Less than 20 cases” (enter a threshold number of cases under which
you will not display the concentration data).
7. You should have a spreadsheet that simply shows County, Total Cases, Concentration, and
Concentration Ranges. 29

8. Login to Microsoft Power BI
(create an account if you don’t
already have one).
9. Click on Get Data, then Excel,
find the spreadsheet you just
created, and click Open. Note
that your spreadsheet will need
to be in Microsoft Excel
Worksheet format for Microsoft
Power BI to import it into your
document.
10. Double click on the name of the
sheet in your spreadsheet and
then click Load.
11. Insert a Filled Map Visualization.
12. Enter County as Location and
Concentration Ranges as Legend.
13. Adjust the formatting as you
prefer to show the variation in
Concentration Ranges by county.
Make the counties with Fewer
than 20 Cases shaded white.
14. Use the automatic Legend or
create your own using shapes
with titles.
15. In order to include the map in
other documents, you will have
to take screen shots.

1. Find the total cases closed with
both brief service and extended
service from your case
management system for the last
three years.
2. Using whichever analysis software
you prefer (Excel pivot table shown
in this example), sort data by legal
problems and limit your review to
the top 10 most prevalent legal
problems.
3. Further sort by Race.
4. Show percentage split between
brief and extended service.
5. Highlight results that deserve
special attention. In this example,
the data relevant to the questions
in the “Multiple analyses are
possible section” above are
highlighted in the table below.

1. Export the total cases closed (including served or not served) from your CMS to a spreadsheet for the most recently
completed year.
2. Sort the cases by zip codes. Review the zip codes and remove any that aren’t actual five-digit zip codes. You may
have to combine data if zip codes show up in multiple ways (such as “87022” and “87022-“)
3. Subtotal the hours worked and number of cases by zip code. Then, calculate the average hours per case for each zip
code.
4. You should have a spreadsheet that simply shows Zip Codes, Total Hours, Total Cases, and Average Hours/Case. You
may want to add a column called “Country” that shows “United States of America” for every row in the spreadsheet
to help with geocoding later.
5. Login to Carto.com (create an account if you don’t already have one).
6. Go to Maps and click on New Map.
7. Click on Connect Dataset and Browse until you find the spreadsheet you just created. Click on Connect Dataset.
8. You may need to go into the Data View to change Zip Codes data from Number format to String format.
9. Still in Data View, click on the orange GEO box in the geometry column and select Postal Codes. Follow the steps to
enter the column name for Postal Codes (Zip Codes in this example) from the drop down menu of fields. For country,
either find the Country field in the drop down list or just type in “United States of America.”
10. Click on Georeference Your Data with Points or Georeference Your Data with Administrative Regions. When using Zip
Codes, select Administrative Regions to get the zip code boundaries to appear on the map.
11. Carto will geocode your data. When it’s done, click on Show. If the map doesn’t appear, click on Map View at the
top of the screen. Zoom in to see your service area.
12. Check out the interesting maps that Carto creates for you or edit the map any way you like.
36

13. Click on the Map Layer Wizard and select Chloropleth. You may change the color ramp, size of markers, number or
buckets and other formatting.
14. If there are outliers (such as zip codes with just one or just a few cases), click on Filter and the select a column to
filter by, or click on the plus sign to add another filter. Select the Cases field and slide the left end of the chart so that
it only shows zip codes with 10 or more cases.
15. You can Add a Layer and go to the data library to find many built-in options, such as state, county or Census tract
boundaries.
16. You can also Change the Basemap to show highways, terrain, satellite images, and other options.
17. Save your map by giving it a new name and clicking Save.
18. In order to include the map in other documents, you will have to take screen shots.
