Answer 1

select  case group_id()
          when 0 then location
          else null
        end location,
        case group_id()
          when 0 then to_char(sum(male))
          else 'Genders'
        end male,
        case group_id()
          when 0 then sum(female)
          else sum(male) + sum(female)
        end female
  from  table_test t
  group by grouping sets((location),(location))
  order by t.location,
           group_id()
LOCATION             MALE           FEMALE
AK                   1                   2
                     Genders             3
NM                   0                   1
                     Genders             1
Tx                   3                   6
                     Genders             9
