A key gauge of the current state of the economy stood above the boom-or-bust threshold of 50 percent in November for the fourth straight month, the government said Wednesday.

Propelled by strong industrial production and a healthy job offers-to-seekers ratio, the index of coincident economic indicators stood at 66.7 percent, the Cabinet Office said in a preliminary report.

A reading above 50 percent is considered a sign of economic expansion. A figure below that line is a sign of contraction.
