This week, the world has been honouring the memory of civil rights leader Martin Luther King Jr.

King had a dream to live in a society where people were judged by their character rather than the colour of their skin.

But that dream was shattered by an assassin's bullet on the balcony of the Lorraine Motel in Memphis, Tennessee, on April 4, 1968. King was 39 years old.

Five decades later, on the anniversary of his death, people across the US and the world paused to remember what happened and what King stood for.

How much progress have black Americans made in the struggle to achieve racial and economic equality?
