More than 57,000 people are in jail in Cuba, according to a rare report about the prison population published by the Communist Party newspaper, Granma.

古巴共产党报《格拉玛报》罕见地发表了一篇报告，称古巴境内有57000多名囚犯。

Granma said efforts had been made to improve conditions for the 57,337 inmates¹, and that 23,000 had prison jobs and were being paid.

Dissident groups have put the prison population between 70,00 and 100,000.

Granma's report came as a UN panel held a hearing on Cuba, including alleged² degrading treatment of inmates.

The article in Granma said rehabilitation³（复原） programmes were under way, with education and training being provided at all levels.

It noted⁴ that an investment plan running until 2017 aimed to improve prison infrastructure⁵ and improve living conditions for inmates.

About half of the inmates were in open jails, Granma said.

And the 23,000 prisoners who were working were being paid the same amount as other workers, the paper added.

Dissidents groups say prisoners are used to work for government-owned businesses but receive very little, if any（若有的话） , pay.
