CPU demand is a derived metric that is made up of multiple sub-metrics (in this case CPU usage, CPU ready, and so on), and is used to estimate the amount of CPU an object actually wants to consume.

Demand is a useful way to manage capacity, since a virtual machine will rarely use all the CPU it has been configured with; this is the basic principle of over commitment. You will also find that demand usually matches the Usage % metric, which is observed inside the vCenter web client.
