In January of this year our IVA (a goods and services tax) jumped from 11% to 16% automatically raising the cost of almost everything. Gasoline has been climbing steadily and is now about US$3.70/gal.
It's still cheaper to live here than many other places in the industrialized world.
Here's an interesting chart I found online. I say interesting because I seriously doubt this was prepared by a Mexican. I mean, where are the beans and tortillas? No habaneros peppers or at least some Melinda's Hot Sauce! But that written, US$205/month is pretty cheap but the minimum wage here is only about US$5/day and this so-called balanced diet costs over US$6. Oops... A very decent wage of $1200pesos per week results in a monthly income of about US$369. Not a lot left over to feed the kids, buy them clothes, send them to school... Times are tough for the locals and with rising prices, aren't getting better anytime soon.
