If you randomly chose a household from Mexico's middle class, this is what you'd find, according to a just published study by INEGI.
The family has:
- a computer
- spends $1,460 (about US$115) monthly on food and beverages outside the home
- has a credit card
At least one family member is a salaried employee with a written contract with a private sector firm.
The head of household is married and has an education that, at a minimum, requires 2-4 years of schooling or training after completing secondary school (the equivalent of 9th grade in the US).
The children of the 4 member family attend public schools.
INEGI cautions that its study is NOT definitive. It does conclude that 39.2% of Mexicans (42.4% of households) were "middle class" in 2010. That is up from 35.3% of the population (38.4% of households) ten years earlier.
