I guess if it's anonymized they just want to find patterns. So if 70% of men aged 40-65 who "flies to the Bahamas often" also like to eat at the local 5-star restaurant there, they can go to that restaurant and tell them to either join the Visa Perks experience to reach the other 30%, or maybe tell them to put out ads at the airport. You can even tell them which months these visitors like to come, so you can time those ads...
