Calculate Percentage based on Filter

[0Experience]

Hello,

I have several locations categorized into different zones. For instance, Loc_1 and Loc_2 belong to Zone N, and Zone C respectively, with their summation being 9.

I can count this using

Sum_of_All_Zone_Loc_Pop_filter = 
CALCULATE(
    SUM(Table1[Loc_Pop]), 
    Table1[Category] = "Cat_total"
)

Now, what I aim to accomplish is determining the percentage of these two selected locations (Loc_1, Loc_2) relative to all locations within their respective zones. For instance, if the count of these selected locations within Zone N and Zone C is 9, and the total count of all locations within these zones is 23.

I am trying to do this the following formula (but not giving the actual result, as I don't know how I can filter the locations based on the zones)

Percentage_of_Zones = FORMAT(
                            DIVIDE(
                                CALCULATE(SUM(Table1[Loc_Pop]),
                                Table1[Category] = "Cat_total"),

                                CALCULATE(SUM(Table1[Loc_Pop]),
                                ALL(Table1[Location]),
                                Table1[Category] = "Cat_total")
                            ),
                            "0.00%"
                            )

Any insights or suggestions would be greatly appreciated. Thank you for your time and assistance.

Try adding VALUES ( Table1[Zone] ) to preserve the Zone context associated with Loc_1 and Loc_2. Otherwise, you'll pick up zones associated with other locations (zones S and E) in your denominator.

Percentage_of_Zones =
FORMAT (
    DIVIDE (
        CALCULATE (
            SUM ( Table1[Loc_Pop] ),
            Table1[Category] = "Cat_total"
        ),
        CALCULATE (
            SUM ( Table1[Loc_Pop] ),
            ALL ( Table1[Location] ),
            VALUES ( Table1[Zone] ),
            Table1[Category] = "Cat_total"
        )
    ),
    "0.00%"
)
