The term "income" has a meaning not applicable here:

The program does not do any calculations.  What are you trying to
achieve?  Do you want to ouput all names of people who are less than
1.6m and over 2m?  That would be a selection of the data which I
cannot see in your program.

Example

irb(main):006:0> heights = {"foo"=>1.0, "bar"=>1.8, "baz" => 2.1}
=> {"foo"=>1.0, "bar"=>1.8, "baz"=>2.1}
irb(main):007:0> puts heights.select {|n,h| h < 1.6}.map {|n, h| n}
foo
=> nil
irb(main):008:0> puts heights.select {|n,h| h < 2}.map {|n, h| n}
foo
bar
=> nil
irb(main):009:0> puts heights.select {|n,h| h >= 2}.map {|n, h| n}
baz
=> nil

You lost me here completely.  What are you trying to say?

Kind regards
