How to check if the sample represents the population data?

Now, I have drawn a sample using Proportionate stratified random sampling technique.

 name designation group division pay-scale Erik Meza IT Project Manager A AB [24000, 45000) Mark Scott project lead A AB [45000, 60000) Jennifer Smith IT Project Manager A BB [60000, 85000) Scott Long hardware technician A CB [24000, 45000) Phillip Smith project lead A CB [60000, 85000)

enter image description here

This is a table which shows how much each group contribute to the population and sample respectively. I am not able to copy paste this table therefore I am adding a picture sorry for the inconvenience. I would like to know what metrics I could use to check if the sample represents the population for such a sample. Any resurces will be useful. Thankyou!
