Human Factors
After departure and out of sterile; the A Flight Attendant called to inquire if we had an armed individual onboard as her manifest showed that. I informed her no one had advised me or presented me with any LEO paper work or credentials. We began discussing other manifest anomalies including a CEO/Must Ride sitting where one of our reciprocating jump seater was sitting. I then asked her to come to the cockpit and bring her paperwork to discuss it further. Once it was determined that there were other errors on the manifest I asked her to go back and do a passenger count. A discrepancy of 12 passengers was determined. It was then noted that the Gate Agents had given us a manifest dated [incorrectly]. We counted all extra passengers as adults and calculated we were 2300 Lbs. heavier than expected at Take Off and adjusted our Landing Weight accordingly. I then rechecked our T.O. numbers to see if we had exceeded any performance limitation weights; which we hadn't; but the V speeds were approximately 2-3 knots slower than desired.More thorough training and supervision of station personnel.More auditing from management.
[Report Narrative Contained No Additional Information.]
A320 flight crew reported discovering several anomalies in the weight and balance data after takeoff. Apparently station personnel used numbers from a flight on a different date.
