How to Measure Disasters’ Impact on Supply Chains

The March 20 disaster declaration identified the following counties impacted by the storm:

• Kent
• Newport
• Providence
• Washington

With this information, we can generate a Business Profile for this disaster region which will give us a detailed picture of affected sectors and residents.

In the examples below, we select the ‘Region View’ from the CBB dashboard. From here, select Edit Region > Prebuilt Regions > FEMA Declared Disaster Regions, and select the ‘4766-Rhode Island Severe Storms and Flooding’ from the Prebuilt Regions menu. You may need to adjust the date ranges to identify the correct event.

Once selected, we can view the data from this disaster in the CBB dashboard.

We can review several categories available through the CBB dashboard and in the Business Profile. For example, the top five Imports for Rhode Island, sourced from the International Trade Data Program:

• Vehicles Other than Railway or Tramway Rolling Stock, and Parts and Accessories Thereof.
• Mineral Fuels, Mineral Oils and Products of Their Distillation; Bituminous Substances; Mineral Waxes.
• Electric Machinery and Equipment and Parts Thereof
• Salt; Sulfur; Earths and Stone; Plastering Materials, Lime and Cement
• Wood and Articles of Wood; Wood Charcoal

Also available: the sectors and products most affected by the disaster (Figure 1). Select the ‘Report’ button at the bottom left corner of the dashboard to generate the CBB Business Profile.

The ‘Top Impacted Sectors table in Figure 1 shows the percentage of national employment by sector in the disaster area.

These numbers were derived by dividing the total employment for each sector within the selected area by the total U.S. employment for that sector.

These are the most heavily represented economic sectors in terms of employment and could be strong indicators of the region’s economy. If these sectors are affected, the entire region’s employment would be impacted.

Based on their percentage of national employment, the top two sectors in the Rhode Island disaster region are Educational Services (61) and Finance and Insurance (52).

Any impact on these sectors would also affect the products produced and shipped for these sectors. For example, Sector (61) generated over $165 million worth of products, according to the 2017 Economic Census. Among them: Professional Training Programs and Educational Support Services.

The Business Summary section illustrates the potential economic impact in the Rhode Island disaster region.

Of the area’s 27,760 employer establishments, 74% were small businesses with fewer than 10 employees, according to the 2022 County Business Patterns. (Figure 2).

More than 17% of the region’s 1 million residents were over the age of 65, and 5% were children under 5, according to the 2017-2022 American Community Survey. These vulnerable age groups made up about 22% of the population (Figure 3). 

Although the average income in this region was over $100,000, 11.4% of the population were living in poverty. An additional 13.6% were disabled (Figure 4). These groups can be especially vulnerable to disasters and when combined, they made up nearly a quarter of the population.

We presented just one example of how the CBB dashboard and Business Profile can help analyze the impact of a disaster on a single area.

Users can add one or more industries to determine the impact to specific economic sectors. They can also customize the map, add and remove map variables, apply filters and compare one county to another within the dashboard.

The Census Bureau's Emergency Management / Disasters page provides quick access to resilience estimates as well as demographic, business and economic data for different types of disasters.
