Esri’s Economic Dependency Ratio: Number and Index

[JillPlescher]

I would like to know what it means when running reports with the variables Age Dependency Ratios and the Economic Dependency Ratios there are two options to run the report  - # and index.  

The definition in the information box is The Total Economic Dependency Ratio is the sum of the population under 16, the population not employed aged 16 to 64, and the population not employed aged 65 and older divided by the total employed population. This ratio is then multiplied by 100.

Assuming this is the number (#) results.  What does the Index number mean?

Good Afternoon Jill,

Thank you for your post. I've attached information on the Esri Dependency Ratios which I think will answer all your questions.

Thank you, Alice

Yes I have read the PDF you posted.  I might be missing something obvious because that doesn't answer what the Index option is when running a report.

Hi Jill, here is some more information for you:  

Index - Age Dependency Ratio (ADR) Definition

The ADR Index is calculated as the ratio of the local child population (aged 0 – 17) and senior population (aged 65+) to the working-age population (aged 18 – 64) in the area relative to the US ADR, multiplied by 100. The ADR expressed as an index is a complementary measure that quantifies how low or high a local ADR is in comparison to the ADR nationwide.

Also, this Data Lesson will provide information on how to interpret the data.
