VOA Report --------Many of the fifty countries rated as least developed have had strong economic growth in recent years. More than half recorded average yearly growth rates of four percent or more between two thousand and two thousand four. The report notes the effects of economic reforms, and the gains that oil producing countries have made from high oil prices.

More than half recorded average yearly growth rates of four percent or more between two thousand and two thousand four. ---------Is it a sentence or a phrase? I don't understand it.
