I placed this around the functions in the derived table

CAST (SUM(case when GeoResolutionCode = 1 then 1 else 0 end)AS FLOAT) Coordinate,

and then rounded them on the outer selection...

Looks about right.

Try

SUM(Coordinate/Total*100.00) Coordinate

Street_Name,

Postcode,

District,

City,

Region,

[State],

CRESTA,

Country,

[None]

FROM (

SELECT

CONTRY_NAME_LC,

COUNT(GeoResolutionCode) as Total,

SUM(case when GeoResolutionCode = 1 then 1 else 0 end)...
