The population of the city is three times what it was in the 1970's.这个句子中what做什么成分?
为什么times后面没有than?

这是一个常用的表达倍数的句型啊,即：倍数词 + 名词性成分（其后无than）
what it is in the 1970's是名词性从句,而what即充当该从句的引导词,又在从句中充当is的表语.
再如：The length of the room is three times its width.
这个房间的长度是宽度的三倍.
再如：I‘m three times older than you.
= I'm three times as old as you.
