The unemployment rate is expected to rise when official figures are released today, adding to the recent run of poor data facing the Reserve Bank.

A survey of 27 economists by Bloomberg has found the average estimate is for the jobless rate to rise to 6.3 per cent for November.

That would be up from 6.2 per cent the month before.

Only one economist expects the jobless rate to fall, while 11 see it staying steady. A couple of the more pessimistic forecasters expect a jump to 6.4 per cent.

Ivan Colhoun, NAB's chief markets economist, does not expect a rise today will force the Reserve Bank's hand on more interest rate cuts.

"I don't think there's ever one number that would make them flick the switch. It would always be their forecast of where unemployment's going to," he said.

"Have they changed that view? Have they changed the view about how quickly the Australian economy will recover to something more like trend growth?"

Many analysts still have concerns about the data's accuracy .

The Bureau of Statistics this week released an independent report into the labour force figures after several wild swings in the seasonally adjusted unemployment rate over recent months forced it to adjust its methodology.

Mr Colhoun said that has caused economists to focus on the more stable trend figure more than ever.

"Economists in general are having a lot of trouble forecasting this number because of the problems the ABS has had with it, so we're tending to look at where we think the trend is for employment growth," he said.

Ivan Colhoun expects jobs growth, but not enough to stop the unemployment rate rising.
