[An Article/Articles] About [A Person/People]

I wonder how to use plurality to express

"Wikipedia articles (each describes about one person) provide their birth date, occupations and nationality.

Maybe one of:

• Wikipedia articles about people often provide their birth date, occupations and nationality.
• Wikipedia articles about a person often provide her/his birth date, occupations and nationality.
• An Wikipedia article about a person often provides her/his birth date, occupations and nationality.
