The easiest way to do this is map with a bunch of if-else conditions.

julia> df = DataFrame(age = [81, 42, 18, 55, 23, 35]);

julia> function bin_age(age)
           if age > 70 
               "70+"
           elseif age > 60  
               "60-69"
           elseif age > 50
               "50-59"
           elseif age > 40
               "40-49"
           elseif age > 30
               "30-39"
           elseif age > 20
               "20-29"
           elseif age > 10
               "10-19"
           end
       end;

julia> df.agerange = bin_age.(df.age);

julia> df
6×2 DataFrame
 Row │ age    agerange 
     │ Int64  String   
─────┼─────────────────
   1 │    81  70+
   2 │    42  40-49
   3 │    18  10-19
   4 │    55  50-59
   5 │    23  20-29
