Abstract
Quinquennial and decade-wise simple growth rates and instability for lac production in India over a 65 year period have been computed. The data revealed that except during thirties, fifties and nineties, the growth rates were negative. Highest negative growth rate and instability was witnessed during the sixties. Study of the year-wise per cent fluctuation from trend line established that the shortfall in lac production is not cyclic in nature.
