Percentage of population

[slhangen]

I have 2 tables with a related field called School.

One table, ContactData, has columns with student name and school name.

The other table, School Size, has 2 columns: school name and school population.

I need to display the % of interventions for selected school.

For example:

In the School Size table, school A has a popualation of 500. 

In the ContactData table, there is 450 rows of contacts for school A.

How do I construct a measue that gives me the 450/500 or 90% I can use in a visual?

Thx community in advance!

Hi, it sounds like you'd like to calculate the population share that is registered with a name out of the total population for that school.

Perhaps try if this works and is what you seek by selecting the School-field and the measure in for example a table visual.

PopulationShare = Divide(Distinctcount(ContactData[StudentName]) , SchoolSize[SchoolPopulation])

Not able to pull in Population. See attached picture for schema. Thx for your assistance.
