Waitlist Length

Number of eligible beneficiaries waiting to access services, indicating unmet demand

What is Waitlist Length?

Waitlist length is the number of people waiting for a service at a point in time. It shows how much unmet demand there is.

Long waiting lists mean delays for those in need, and are an important signal for planning capacity.

Count of individuals on active service waitlist at point in time

How to calculate it

Count the individuals on the active waitlist at a point in time.

For example, if 340 people are on the waitlist at the end of the month, the length is 340.

Track the time people wait as well as the count, and remove people who no longer need the service so the list stays accurate.
