I can't figure out what you are asking, so I just give you what I would use: 
#!/usr/bin/perl

use strict;
use warnings;
    
# Deal with first two lines.
chomp ($_ = <DATA>);
print "$_      Total\n";
chomp ($_ = <DATA>);
print "$_     ------\n";
    
my (@total, $grand_total);

<DATA> for 1 .. 2;  # Skip first two lines.
while (<DATA>) {    # Read in line by line
    chomp;
    my ($county, @years) = /\d+/g;    # Extract numbers from line.
    my $sum;
    for (my $i = 0; $i < @years;$i ++) {
        $sum       += $years[$i];     # County totals.
        $total[$i] += $years[$i];     # Year totals.
    }
    printf "%s %10d\n", $_, $sum;     # Print line, with county total.
}
$grand_total += $_ for @total;
 
 
# Final two lines, print yearly totals.
 
print "           ------     ------     ------     ------     ------\n
+";
print " Total";
printf " %10d", $_ for @total, $grand_total;
print "\n";
