Space-time distribution and mutual correlation of the N--S asymmetry in various indices of solar activity are considered. It is shown that changes in the N--S asymmetry variation both at short and long time scales are consonant in all activity indices under consideration. Quasi-biennial variations of the asymmetry index and their space-time distribution are revealed and examined. The conclusion can be drawn that the N-S asymmetry is a specific independent and very promising tool for analysis of the solar activity variations.
