The single received generally favorable reviews from critics. Carl Williott of Idolator wrote in a review, "'People Like Us' showcases Kelly’s ability to turn frustration into uplifting (and danceable) catharsis. With lines like 'We are all misfits livin' in a world on fire,' it’s another colossal, fist-in-the-air pop anthem from Clarkson." Andy Scott of Celebuzz also wrote a positive review, remarking: "the latest single from the Grammy-winning superstar is exactly what we've come to expect from her: infectious beats; uplifting lyrics; and a powerful chorus that reminds one of her past hits like "Since U Been Gone" and "Stronger (What Doesn't Kill You)". Multiple music critics also considered it to be a gay anthem. Zara Golden of VH1 compared the song's lyrical theme to Lady Gaga's "Born This Way" (2011), but also noted that "Clarkson is an old expert at spinning hope from hard times and this is the perfect final entry to Clarkson’s 'Chapter One.'"
