Why not create the anonymous hashs?like,

for my $i (1 .. 3) {
    push @userData {'user' .$i => 'value1', 'key2' => 'value2' ...};
}

or maybe a HoH is better,as,

my %HoH = ( 'user1' => { key1 => value1,key2 => value2...},
                     'user2' => { key1 => value1,key2 => value2...}
                    ...
                   );

If you really want to use a variable as hash's names,you may need to
eval a string,which is not good so.
