Facebook monthly active users

Facebook MAUs going up, American librarians going down. The platform that scaled to three billion monthly users is not, technically, replacing the reference desk. Yet the ledger reads what it reads.

Facebook MAUs grew from about 360 million in 2009 to nearly 3 billion by 2022 as the platform absorbed the global mobile internet. US librarians employed declined as municipal budgets tightened and library systems shifted toward part-time and paraprofessional staffing. The negative correlation reflects two genuinely related stories: as social platforms became the default information layer, traditional public-library funding pressure compounded, and the same decade scaled one infrastructure while quietly trimming another. The information economy moved.

Information moved venues. The platform grew and the public reference desk thinned.
