Should My Resume Have a 'References' Section?

I see a lot of resumes that have a 'References' section.
I have often wondered whether it is a good idea or a waste of space.
An example of this is below, the 'References' section causes this resume to go from 1-page to 2-pages; so is it really worth having? 

 

I took this question to the experts and here is what they had to say:

References are a must! When you're on the job search having some references ready to go is important but they don't need to be on your resume. Just saying "references upon request" at the end of a resume will tell the employer you have references and will provide them when they ask.

This also helps make sure that you’re not sharing your reference's phone number/contact information openly with everyone that stumbles upon your resume.

References should be separate from the resume and cover letter. Why?

First you (the candidate) don’t know what types of references the company will want. Recently I’ve seen that companies are requesting references from (1) managers (2) co-workers or peers, and (3) personal. The best reason to NOT include references with your resume is this gives the candidate an opportunity to contact the hiring manager. If you have not heard from the company you really want to work for, you can drop them a short note thanking then again for their time and expressing your interest in working for this company and providing your references in case they would like to contact them for more information about your skills, experiences, and capabilities.
