The authors use this figure to illustrate Engel's Law: as incomes rise households spend a smaller proportion of their income on foodstuffs. The figure demonstrates this point excellently. More interesting than this broader trend, however, are the quirks in consumption unique to each country. The high cost of American health care is easy to spot here, as is the high proportion of income South Koreans spend on education. What sticks out most to me, however, is Hong Kong. People in Hong Kong devote a whopping 17% of their annual consumption on clothes and shoes, This is not only five times what other developed countries are spending on apparel; it is also more than Hong Kongers spend on housing, health care, or transportation!
I encourage you to page through the report and find your own favorite figure from it.
EDIT: 15/05/2015 - Trey Menefee was able to track down a similar data set from a different source:
@Scholars_Stage the numbers are really off. Clothing/shoes are 3% of household expenditures https://t.co/LPaxxdQG72 pic.twitter.com/xhBYWplkJ3— Trey Menefee (@trey_menefee) May 13, 2016
Trey suggests--as did the commentator "Bormington" below--that the APO numbers probably come from sloppy compilation of data that counted tourist purchases along with regular household consumption. I agree that this is the most plausible explanation for the discrepancy.
