Prezada Kila, Yes, it is well used in European Portuguese, but in an informal way. In fact, there is a popular song : Não Há Gente Como a Gente. Saludos, Antonio

Kila, sorry I am not a native speaker of Portuguese but I have some experience with this Portuguese word. They use it in the almost the same way as your PEOPLE. ( Ex.: A genete ali é do Barsil ). The Portuguese use it too, but more in an informal way.

"A gente" is used with the meaning of "nós" in familiar, informal, everyday usage. It requires the verb in the 3rd person singular and if the expression is used with an adjective, this should be in the feminine form, e.g. "A gente está cansada". There is also the expression "toda a gente", which means everybody.. "Já alertámos toda a gente, mas não nos apresentam qualquer solução." "Creio que toda a gente já ouviu falar de Winston Churchill." https://ciberduvidas.iscte-iul.pt/consultorio/perguntas/nos-e-a-gente/103

in Brazilian portuguese is used informally, in a impersonal conversation, and it is conjugated in the third person singular, example: " nós somos brasileiros" hás the same meaning of " a gente é brasileiro". But I don't know to tell you if in portuguese of other countries it works the same way
