Explore an equity index

When conducting a racial equity and social justice workflow with GIS, it is crucial to take time to listen and integrate the experiences of those who have been affected by inequity. In this scenario, your department hosted a number of community engagement sessions in partnership with a local community-based organization the community trusts. The discussion focused on better understanding what barriers people faced with access to active transportation like walking and biking, health behaviors like physical inactivity that can contribute to adverse health outcomes, and what challenges they faced with environmental injustice such as disproportionate exposure to air pollutants.

One key message that came out of the discussion was the lack of connectivity in biking routes. The city had many biking paths, but in the areas where there were higher proportions of those living in poverty and communities of color, the paths are disjointed and don't connect to places where people can find good jobs, shop, or easily access green space and parks. Physical inactivity was also a concern, which can negatively contribute to other health concerns, including heart disease, diabetes, cancer, and mental health. Increasing active transportation opportunities not only encourages more activity, but it can prevent and reduce the risk of several chronic diseases.

Out of these conversations, you start to put together a grant application to demonstrate the community's real needs and explain that your proposed plan will meet an important need in areas that have been historically underserved and disproportionately impacted by environmental harms.

Add the index to the map

The grant requires that you use a state-level environmental justice index to demonstrate equity needs in your proposal. You will start by adding this index to your map and exploring the data for your city.

    CalEnviroScreen layer on the map

    CalEnviroScreen is a mapping tool developed by the California Office of Environmental Health Hazard Assessment (OEHHA) that identifies the communities that are most adversely impacted by sources of pollution at the 2010 census tract geography. The OEHHA conducts scientific evaluations that inform, support, and guide policies and regulations related to environmental health hazards and risk in the state of California. One of the strengths of the CalEnviroScreen tool is that it considers the cumulative impacts of exposure risk to environmental hazards, groups of people who might be especially sensitive to exposure of pollution, such as those who are under the age of 5 or over the age of 65, and socioeconomic factors. The latest version of CalEnviroScreen is version 4.0, released in October 2021.

    The default view of the map shows the composite index score as a percentile so different communities can be compared by census tract. An area with a high score is one that experiences a much higher pollution burden than areas with low scores. A census tract in the 75th percentile means that it is in the top 25 percent of census tracts with the highest pollution scores.

    Before you begin exploring the data within the index, you will focus your map to the city of Fresno. You will add city boundary data to your map.

    Note:

    For this tutorial, the city of Fresno is being used as an example. This analysis and workflow is not meant to be used as an official recommendation or analysis. This tutorial is intended to be an example to demonstrate how users can use GIS to apply an index to a specific intervention.

    Another way you can add data is through the Catalog pane.

  9. If necessary, click the View tab. In the Windows group, click Catalog Pane.

  17. Click Run.
  18. In the Contents pane, uncheck the CalEnviroScreen 4.0 Results layer to turn it off.

    The FresnoCES layer symbology now shows the composite index score for the census tracts only within the city of Fresno.

    The original layer showed the tract scores across the entire state. It revealed that majority of the tracts within Fresno were among the highest scores in the entire state. But now with this layer only showing tracts within the city, the symbology color range adjusted and you can see which tracts have especially high scores in a city with many high scoring tracts.

    Compared to the state level layer, you now have a more focused map showing where the highest need areas are within the city.

Explore the data

The CalEnviroScreen 4.0 index score is calculated using factors from two groups of indicators:

  • Pollution burden—Ozone, particulate matter (PM2.5), diesel emission, drinking water contaminants, children's lead risk from housing, pesticide use, toxic releases from facilities, traffic, cleanup sites, groundwater threats, hazardous waste, impaired waters, and solid waste sites
  • Population characteristics—Rates of asthma, cardiovascular disease, infants born with low birth weight, education level, housing burden, linguistic isolation, poverty, and unemployment
Note:

To learn more about and explore each of the indicators, see CalEnviroScreen 4.0 Indicator Maps.

The CalEnviroScreen 4.0 Results layer includes fields with data on the number and percent of people by race and ethnicity by census tract. The data is from the 2019 American Community Survey from the U.S. Census and categorized into six groups based on respondents' self-identified ethnicity and race:

  • Hispanic (Hispanic or Latino of any race)
  • White (non-Hispanic)
  • African American
  • Native American
  • Asian American
  • Other Multiple
Note:

To learn more about the CalEnviroScreen methodology and use of race and ethnicity categories, see Analysis of Race/Ethnicity and CalEnviroScreen 4.0 (PDF).

You will explore the indicators and where they are most prevalent within your city.

    Note:

    The race and ethnicity supplemental data included in the CalEnviroScreen 4.0 layer is derived from the U.S. Census Bureau categories for race and ethnicity. While it is a widely accepted data source for determining where people of different backgrounds reside, it is limited and will not adequately capture the full breadth of identities and cultural experiences. There are other methods to calculate the communities of color using the Census Bureau categories for race and ethnicity. For this tutorial, you will use this method for brevity. But it is important to recognize that this method has limitations, as does any other method of calculating for communities of color when using U.S. Census Bureau-collected data.

  11. In the Fields column, double-click White.pct.

    The code for the White (Non-Hispanic) percent field adds to the expression.

  12. Save the project.

You have explored the environmental equity index and several of its indicators in your city. You compared the index values to traffic and airport location data. You calculated the percent of communities of color in your city and styled it so you could compare that information with the index scores.

It is important to consider that not all indices will be applicable for your use case. For example, you may come across another index that is based on a national scale for general health and social vulnerability outcomes, but the lowest level of data available is at the county level. That will not be very informative for a city-level analysis, where a census tract or even block level of disaggregated data will be more specific and meaningful for decision-making. The use of CalEnviroScreen for an environmental justice intervention is appropriate, but it might not be appropriate for determining which areas need more investment in broadband internet access. While the population characteristic indicators in CalEnviroScreen might be informative for building out a broadband internet access network with equity measures, the pollution characteristics have little to do with internet connectivity. It is recommended that when you use an index for decision making, you tailor it for the specific intervention the decision is being made for and to the extent and scope of the project area's unique characteristics.

Now that you have a baseline of understanding for the index, you will add health data and identify which area in the city would most benefit from increased bike path connectivity.


Propose an equity plan

In this section, you will add information about physical inactivity rates in your city. By adding health behavior data, it will help you better focus on which parts of the city are at higher risk for adverse health outcomes and would most benefit from the intervention you will propose. You will use data from the index, the percent of people of color field you calculated earlier in the tutorial, and data on physical inactivity rates to determine your primary focus area for the proposal.

Add health outcome data

You will access data provided by the Centers for Disease Control (CDC). The PLACES dataset includes several health outcome measurements for each census tract level in the United States. The data is derived from modeled survey data conducted by the CDC.

  1. On the ribbon, on the Map tab, in the Layer group, click Add Data.
  2. In the Add Data window, under Portal, click Living Atlas. In the search bar, type cdc places and press Enter.

    Search cdc places in the Add Data window.

    In your target area, there are few existing bike paths and not as many connections. It is important for bike paths to be connected so people can reliably use them to get to school, work, and shops.

    You will also add more contextual layers to better inform where bike path connectivity would benefit the community. You will add layers to show where the parks and public schools are located.

  16. Use what you have learned to add data from ArcGIS Online. Search and add the following layers owned by Learn_ArcGIS:
    • Parks Fresno
    • Public Schools Fresno

    The layers add to the map.

    Park and school locations added to the map

  17. Save the project.

Propose a bike path

You now have all the information you need to propose connecting bike paths with an equity lens. First, you will adjust the symbology of the map so it is more clear before you start drawing the proposed bike paths.

For your focus area, you will show it as the same color, knowing it already represents a combination of indicators your community wanted to prioritize.

  1. In the Contents pane, click the FresnoCES_SpatialJoin layer two times and rename it Project focus area.
  2. In the Contents pane, right-click the Project focus area layer and click Symbology.

Propose connective bike path routes

Now that you have a Proposed bike path type set up, you can begin to draw the complete proposed route plan. First, you must make a copy of the existing Existing_bikepaths layer to draw more routes with the new Proposed type you created.

  1. On the Edit tab, in the Features group, click Create.
  2. In the Create Features pane, in the Existing_bikepaths section, click Proposed.

    The Proposed type BikePath is selected with the line tool is activated.

  3. On the map, add more proposed bike way routes. Consider routes that will add connectivity to the focus area and nearby schools and parks.
    Tip:

    To pan the map with the edit tool activated, press the C key and pan the map. Release the C key to return to using the edit tool.

    There may be many other factors that will be important to consider, such as road width, traffic loads, or areas and routes that might pose safety issues for cyclists. Such considerations are important to implement when proposing routes and should be done in collaboration with community input and other local government agencies that may have specific restrictions and standards for developing bikeways. For this tutorial, you will propose routes assuming these aspects have been accounted for.

  4. When you are finished, on the ribbon, click Save. In the Save Edits window that appears, click Yes.
  5. If necessary, clear any selections.

    You now have a map that shows your proposed bike path proposal in the context of the other important factors that helped you come to this decision.

    Example of proposed bike way routes that connect the target area to existing routes

    At this stage, it is important to create a way for the community and partnering organizations to review and provide feedback on this proposal. It is not uncommon to propose several options and versions of a proposal to help facilitate the discussion on what options will be possible.

In this section, you have added health outcome data, determined the focus area for your project, and drafted a proposed bike path plan to increase active transportation connectivity in areas that the community wants to prioritize based on equity measures. In the next section, you will publish your map into an online web app so you can share the plan with community members and partners.


Publish a policy web app

The most important step when applying racial equity and social justice workflows to GIS is to engage and include the community. You could print the map you've created so far and use that to share with the community. But you can also create an online, interactive digital version of the map that allows viewers to interact with the data, turn layers on and off, and potentially share more widely than with a hard copy map.

Prepare the map and pop-ups

Before you publish the map, you will make some small refinements to your map data so it will be clear and make sense to a wide range of audiences. First, you'll update the layer names.

  1. In the Contents pane, click FresnoCityLimits two times. Type Fresno City Limits and press Enter.
  2. Use what you have learned for the Existing_Bikepaths layer and rename it Bike Paths.

    Next, you will configure pop-ups.

  3. On the map, click a school symbol.

    Pop-up for a school point

    A pop-up appears. It currently contains all the fields for the layer. A lot of this information is not necessary to understand why the bike paths were proposed. The only field you want to show is the school name.

  4. In the Contents pane, right-click Public Schools and click Configure Pop-ups.

    The Configure Pop-ups pane appears.

  5. Point to the Fields element and click the Remove pop-up element button.

    Remove pop-up element button for the Fields element in the Configure Pop-ups pane

  6. On the map, click the public school symbol.

    The pop-up now only shows the name of the school in the pop-up title.

  7. For the Parks layer, use what you have learned to configure the pop-up so only the name of the park is in the title.

    Several of the layers don't need a pop-up, so you will disable them.

  8. In the Contents pane, right-click FresnoCityLimits and click Disable Pop-ups.

    Disable Pop-ups for the FresnoCityLimits layer

  9. Disable the pop-ups for the Existing_Bikepaths and Percent People of Color layers.
  10. In the Contents pane, click Project focus area.
  11. In the Configure Pop-ups pane, double-click the Fields element.

    You want to show the fields that determined the focus area.

  12. Check Display and uncheck it again to uncheck all the fields.

    Check and uncheck Display in the Configure Pop-ups pane

  13. In the list of fields, check the CIscore, PerPOC, and Physical inactivity crude prevalence (%) fields.
  14. Click the back arrow.
  15. Double-click the Title field.

    Pop-up title

  16. Delete the existing text and type Tract {tract}.

    The layer names and pop-ups are configured.

The map is now more user-friendly and ready to publish online.

    In this section, you have prepared your map for publishing to ArcGIS Online and configured it so that it only contains the most important information your viewers will need to comment and provide feedback on the proposed bike path plan. You published the map to ArcGIS Online and created an Instant Apps app, enabling viewers to turn layers on and off and to explore the bike path proposal.

Every application of racial equity and social justice will require several rounds of community engagement and revised versions of a proposed plan. You can use what you have learned in this tutorial to adjust your proposal and publish new versions of the plan online to demonstrate your responsiveness to the received feedback and operationalize a plan that will truly meet the needs and experiences of the communities they are intended for.

In this tutorial, you operationalized an environmental justice index by exploring the data and how it related to your local context. You added health outcome data and other supporting data such as schools, parks, and existing bike paths to inform the best place to propose connective new bike paths with an equity lens. You published the proposal to ArcGIS Online and created an Instant Apps app so you could share the first draft of your plans with the community.
