  • I am so pleased that I found you! I have suffered from Sleep Apnea for years. I have tried everything to fix the problem but nothing has worked. For the last years I have been trying to use a CPAP machine on and off but it is very difficult to sleep with. It's noisy and very uncomfortable. I had no idea there was a natural way to help me. I am so pleased that I found you! ◆◆◆ http://t.cn/AigiN2V1

  8. 8. 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 8 • Click on a question box: o Link to detailed questions  Link to analyses
  9. 9. 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. 9

  25. 25. Example Analyses Steps: 1. Find the total number of intakes from your CMS for the last 5-10 years. 2. Create a table in Excel and enter the annual intake numbers in columns for each year. 3. Open the ACS, Advanced Search. 4. Click on the Geographies blue box on the left side of the screen. 5. Select a geographic type from the drop down based on the most appropriate type for your service area (state, county, census tract, etc.). 6. Click Add TO YOUR SELECTIONS and close the Select Geographies. 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 25 Who requests assistance?

  29. 29. Who do we help? Geographic Concentration Example Analyses Steps: 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

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.

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. 33 Excel

  36. 36. Example Analyses Steps: 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 What resources are required? Geographic Distribution
  37. 37. Example Analyses Steps: 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. 37 What resources are required? Geographic Distribution Carto
