You're welcome. But note that not all users in the passwd file are really "people". i.e. on my Mac there are 65 entries in the passwd file, and there's only me and root (also me) in the vicinity
Special "users" like daemon, nobody, lpr, etc. are used by the system for various functions.
If you have any convention by which user ID's are assigned, you may want to count only those that match.
i.e. assuming that "real" user IDs start from 1000:

vipw
vipw(8) System Manager's Manual vipw(8)NAME
vipw - Edits the /etc/passwd file
SYNOPSIS
/usr/sbin/vipw
DESCRIPTION
You use the vipw command to edit the /etc/passwd file with the editor defined in the EDITOR environment variable. If the variable is not
set, the default editor is vi.
The vipw command performs basic consistency checks on the edited file. If a hashed indexed passwd existed previously, the vipw command
uses the mkpasswd command to create recreate it.
The command must not be used on systems that use extended security attributes since it cannot set or change them. You must be root to run
this command. Only root and security administrators should have execute access to this command.
Since the vipw command cannot effectively change all the attributes of users, it should not be used in a secure environment.
The vipw command accesses the following files, and requires the listed permissions:

Permissions File

rw /etc/passwd

rw /etc/passwd.dir
rw /etc/ptmp
