The richest 2% of the world's population owns more than half of the world's household wealth.
Assets of just $2,200 per adult place a household in the top half of the worlds wealthiest.
To be among the richest 10% of adults in the world, just $61,000 in assets is needed.
If you have more than $500,000, you're part of the richest 1%, the United Nations study says.
Half the world (nearly 3 billion people) live on less than $2 a day.
