Is this an efficient way to get the number of players in a game?

Hello, I have created a script that has a NumberValue in a Folder inside of Workspace. Whenever somebody joins, it adds + 1 to the NumberValue. Whenever someone leaves, it does - 1. I am just curious to know if the way I am doing this is efficient because I know there is other ways of doing this. I also forgot to mention that whenever someone joins it just prints out 0 for some reason. Thanks!

Code:

numbers = game.Workspace.Numbers
value = numbers.PlayerCount.Value

game:GetService("Players").PlayerAdded:Connect(function()
	numbers.PlayerCount.Value = numbers.PlayerCount.Value + 1
	wait(1)
	print(value)
end)

game:GetService("Players").PlayerRemoving:Connect(function()
	numbers.PlayerCount.Value = numbers.PlayerCount.Value - 1
	wait(1)
	print(value)
end)

Thank You!
