While the World Cup is drawing viewers to what's happening inside those soccer stadiums, some local Brazilians are trying to highlight what's going on outside.

They're focusing on what they consider to be the problems of overspending and economic inequality, and there's one issue that has proven to be a big rallying point: housing.

In Sao Paulo, for example, a city of an estimated 11 million people, protesters have taken over abandoned buildings in the midst of the World Cup. The actions point toward a simmering tension over accessing decent housing, says reporter Andalusia Knoll, in Sao Paulo.

"It's estimated that about one million people in the city here in Sao Paulo, which is one of the richest parts of the country, do not have proper housing," said Knoll on Take Two.

That means, they're living in shantytowns, or favelas, that often lack safe water or electricity, she said. She spent time with one group, called the Central Region Housing Movement, that has taken over one abandoned building with 60 families and says it plans to live there long term.
