You are doing ls -la which will list "." and ".." so you need to subtract 2 from your count.

Hope you are ok with perl

Code:
#!/usr/bin/perl

$myDir="/";
my $count=0;
opendir(DIR,$myDir) || die ("Unable to read directory\n");
while($temp_dir = readdir(DIR)) {
	next if($temp_dir=~ /(^\.+$)/);
	opendir(TMPDIR,"$myDir"."/"."$temp_dir") || die ("Unable to open the sub-directory $temp_dir");
	@tmp_sub_dir_list=readdir(TMPDIR);
	$no_of_files=@tmp_sub_dir_list;
 	closedir(TMPDIR);
	if ($no_of_files ==2) {
		print "$myDir"."/"."$temp_dir"."\n";
		$count++;
	}
}	
print STDERR ("The Total number of Empty Dir\t:  $count\n");
closedir(DIR);

you can find empty directories with
Code:
find . -maxdepth 1 -empty -type d

change maxdepth to suit your needs

No, it is not a part of the standard find command. It can be found on the gnu variant of find.
