1. One of the most affluent counties in the country. Once in the top 5 overall wealthiest, now ranks at number 11. Although over 90% of households in the county are well above the national average yearly income, there are several areas in the eastern side of the county which are below the national average(Silver Spring, Kensington, Montgomery Village, and Wheaton). MoCo also has areas which boast average individual incomes over $86,000/yr. Putting the cities of Olney, Bethesda, and Potomac in the top 200 highest average idividual income in the nation, with a population over 10,000.
A recent study by MSN has shown that in order to live the lifestyle that a $100,000/yr would provide the average American, you would need to make more that $150,000/yr. Putting MoCo in the top 3% in the nation.

Suburban county of Maryland

One of the few counties where there's a ghetto area (Wheaton, Silver Spring), there's a rich-ass area (Bethesda, Potomac), and the boonies (Damascus, Poolesville) all crammed together.
That's diversity for you.

One of the richest counties in America. To sound cool, we say we're from D.C. but really, everyone can tell we're MoCo at heart.
Person A: Where are you from?
Person B: Washington, D.C.
A: But you have a Louis Vuitton bag and drive a BMW.
B: I'm from Georgetown.
A: Liar! You're from Potomac aren't you?

1) Montgomery County, Maryland. In it;s location right next to DC, it has DC's violence in some parts, while it also has the richness of Orange County California.

2) Home to many of the 2002 sniper shootings.

MoCo is only used for Montgomery County Maryland. If you use it to define some other Montgomery County, I will personally jump you.
Let's all visit MoCo for some fun fun fun!

The county where everyone is either straight out of the OC or tryin to be ghetto. But the love is all in MoCo. And whoever thinks that we stole the MoCo from Howard County, it should be pointed out that Howard County is HoCo. And yes, their girls are hos.
Girl from MoCo: Yeah, I got into every college I applied to!
Guy from PG County: What is college?
