US racial segregation laws officially ended in the 1960s, but does the massacre of black churchgoers, and a string of black killings and abuse by police, mean that racism still thrives? At 1930 GMT Monday, The Stream explores how racism has changed over the years, and how some black Americans are coping.

Unequal opportunities have left 600 million children living in extreme poverty, according to UNICEF. These children are chronically malnourished, twice as likely to die from preventable causes before the age of five, and are far less likely to achieve minimum reading standards. These are some of the findings of a United Nations Children's Fund (UNICEF) report on the Millennium Development Goals (MDGs).

UNICEF described the report as its "final report card" on the impact of MDGs on the lives of children around the world. While "MGDs helped the world realise tremendous progress for children", the UNICEF executive director said, "in the rush to make that progress, many focused on the easiest-to-reach children and communities, not those in greatest need".

The Millennium Development Goals are a set of eight benchmarks that were established by the United Nations in 2000 to measure progress in reducing child mortality, eradicating hunger, poverty, achieving universal primary education, improving maternal health, combating diseases, ensuring environment sustainability and establishing a global partnership for development.

With MDGs set to expire at the end of the year, the United Nations is introducing a new set of benchmarks called the Sustainable Development Goals (SDGs). The SDGs will replace the current MDGs as the new targets for addressing global poverty, inequality and climate change for the next 15 years. The UN has called on world leaders to put children at the centre of these new goals.
