Just thought I'd share: http://www.indexcreditcards.com/finance/creditcardstatistics/2011-report-on-credit-card-usage-facts-...
1.4 billion cards in circulation
181 million cardholders (77% of adults)
7.7 average # cards per cardholder
Visa accounts for 38.5% of swipes
MC 24.3%
Amex 23.2%
Discover + all others 14%
Visa 111 million cardholders
MC 98 million
Amex 44 million
Amex cardholders spend on average 55% more per year on their credit cards than Visa cardholders, 115% more than MC cardholders (although this statistic is likely inflated b/c people with both an Amex and Visa may choose to use their Amex more often)
Average person uses a credit card 119 times a year charging an average of $88 per transaction, or $10500 annually
There were 20 billion transactions last year with a monetary value 12.9% of the GDP
Credit crunch or not, looks like credit cards are here to stay!
