According to Vedic astrology, when Mars is deposited in any of the 1st, 4th, 7th, 8th & 12th Houses in the Birth Chart, the Native is termed as mangalik. There is a total of 12 (Twelve) houses in a horoscope or birth chart or kundali and 7 natural planets (Sun, Moon, Mars, Mercury, Jupiter, Venus & Saturn) and 2 shadow planets (Rahu & Ketu). From this it is evident that Mars deposited or placed in any one of the Five houses out of the total Twelve houses of a birth chart, makes the native Mangalik. Therefore, according to this interpretation, 41.67% of the total human population becomes Mangalik. Some Astrologers also treat placement of Mars in 2nd House as Mangalik. Thus 50% of the total population may be treated as Mangalik. In fact, this should not be treated in general as a Mangalik Dosha.
