| * Trend in union density rates is calculated for wage and salary earners. Where the union density rates for wage and salary earners are not available, the trend is calculated for non-agricultural labour force or for formal sector employment. Key for trend symbols: ++ change in union density rates is larger than +20 per cent; + change in union density rate is larger than +5 per cent, but not larger than +20 per cent; -- change in union density rate is larger than -20 per cent; - change in union density rate is larger than -5 per cent, but not larger than -20 per cent; = change in union density rate is not larger than +5 per cent. The trend is calculated on the basis of a 10-year period. If the number of years is shorter, trend scores are adjusted accordingly. | ||||||||
