How many people are Manglik?

Ask whether someone is Manglik and the answer depends less on their chart than on which rule the astrologer uses. Several versions are in daily use. We took 60,000 birth moments, cast a chart for each, and counted how many each version marks Manglik, from the most common rule down to the words of the classical text it comes from.

Results

Each version below adds or removes one thing. The striped bars are later additions that the classical verse does not contain; the solid bars follow the verse.

Out of 60,000 charts. Shares are rounded to one decimal place.

Why the popular rule catches almost everyone. Six of the twelve houses count, so from any single starting point Mars lands in one of them about half the time. The popular rule counts from three starting points (the ascendant, the Moon and Venus) and calls the chart Manglik if any one of them hits. Three chances at roughly one in two each leave only about one chart in eight unmarked: by simple arithmetic about 87.5% are marked, and we measured 87.9%.

What the verse removes. Dropping the 2nd house and the counts from the Moon and Venus takes the share from 87.9% to 41.8%. The verse’s own exception, a benefic planet joining Mars or aspecting it, removes about half of the rest, leaving 21.4%. On any given day only a small part of those are in a period of Mars: 2.4% of all charts on 11 September 2026.

The six cities agree

The figures hardly move from city to city: in every column below the six cities are within 1.2 percentage points of each other. Mars’s house depends on the time of birth far more than on the place.

10,000 charts per city.

The rules, word for word

The verse: BPHS 80.47

Mangal is Mars; Lagn is the ascendant. The verse sits in chapter 80, which deals with women’s birth charts; verses 48 and 49 apply the same placement to men. The English translation names four houses. The Sanskrit line opens with lagne, “in the ascendant”, which makes the 1st house a fifth place; Supastro follows the Sanskrit. Read with four houses, as the English has it, the share would be 33.3% instead of 41.8%.

The verse’s own exception: a benefic on Mars

The same verse ends “without aspect by, or association with any benefic”. Which planets count as benefics is set out in BPHS 3.11:

So the benefics are Jupiter, Venus, a waxing Moon, and Mercury when no malefic sits with it. Mercury in the same sign as Mars is therefore not a benefic, because Mars is a malefic. Which houses a planet aspects comes from BPHS 26.2–5:

In this study, the exception applies when Jupiter, Venus or a waxing Moon is in the same sign as Mars, when Mars is 5th, 7th or 9th from Jupiter (Jupiter’s aspects), or when Venus, a waxing Moon or Mercury free of malefics is 7th from Mars (directly opposite).

When both partners have it: BPHS 80.48–49

This is a rule about a couple, so it does not change how many single charts are marked. It matters for matching, below.

What the later versions add

• The 2nd house. BPHS 80.47 does not list it. Supastro’s verse database, which compares each rule with the classical texts, found no classical verse that adds it.
• Counting again from the Moon. The nearest classical line is Brihat Jataka 24.9, about “the 7th house from the Ascendant or the Moon-occupied sign [be] occupied by several malefic planets”: several harsh planets in one house, not Mars alone.
• Counting again from Venus. We found no verse for it.
• Extra exceptions such as Mars in its own sign (Aries or Scorpio), exalted in Capricorn, in Leo or Aquarius, or in certain house and sign pairs. We found no verse for these either. Supastro still lists them, as later exceptions that soften the verse’s form but do not cancel it; they do not change the figures above.
• The name. A word search finds neither “Manglik” nor “Kuja dosha” in the six classical texts in our library (Brihat Parashara Hora Shastra, Brihat Jataka, Phaladeepika, Jataka Parijata, Uttara Kalamrita and Laghu Parashari). The rule is in BPHS 80.47; the names came later.

How we did it

• 60,000 generated birth moments, not people. Each is a whole minute picked at random between 1 January 1980 and 31 December 2005, Indian Standard Time, with a fixed seed (20260911) so the same list comes out every time. 10,000 each were placed in New Delhi, Mumbai, Kolkata, Chennai, Bengaluru and Hyderabad.
• One chart engine. Every chart was cast by Supastro’s own chart engine, the one its free tools run on, including the free Manglik check: sidereal zodiac (measured against the fixed stars, as Indian astrology does), Lahiri ayanamsa (India’s standard correction between the Western and the sidereal zodiac), whole-sign houses (each house is one whole sign, starting from the ascendant’s sign) and the mean lunar node.
• One Manglik rule set. Every flag comes from the same Manglik function that the free check, Supastro’s paid readings and its reports use; nothing was re-coded for the study. As a cross-check, the yoga and dosha engine behind Supastro’s readings gave the same in-force verdict on all 60,000 of 60,000 charts.
• Mars period. A chart counts as “in a Mars period” when its Vimshottari dasha had a Mars main period or sub-period running at 12:00 IST on 11 September 2026, the date of our earlier census, kept so the figures compare.
• Checkable. The sample file lists every birth moment and city with Mars’s house from the ascendant, the Moon and Venus and every flag, so anyone can recast a chart in other software and check its row.

Change from our earlier figures. The same sample appeared in our dosha census, which gave 22.3% after the exception and 2.5% in a Mars period. Since 11 November 2026 Supastro also counts a waxing Moon opposite Mars (its 7th-house aspect) as a benefic aspect, as BPHS 26.2–5 and 3.11 give. That moves those two figures to 21.4% and 2.4%; every other figure is unchanged.

Limitations

• Generated moments, not a population. Real births are not spread evenly across hours, seasons and years, so the share among real people can differ a little. The figures describe the rules, not any group of people.
• Six Indian cities, births from 1980 to 2005. Other places and decades may give slightly different shares; we have not measured them.
• Birth time decides. The ascendant changes sign about every two hours, so a birth time off by a few minutes near the edge of a sign can move Mars into another house.
• Rules as coded. Each figure is for the rule exactly as described on this page. Schools that use other house systems or other exceptions will get other numbers.
• One day. The Mars-period figure is for 11 September 2026 and changes from day to day.

What it means for marriage matching

A label that the popular rule gives to about 9 people in 10 cannot single anyone out. Even by the verse, about 4 in 10 charts have Mars in one of its houses, and about 1 in 5 keep it after the verse’s own exception.

Manglik is one factor among many, and it belongs to both charts, not one. BPHS 80.48–49 voids it when both partners have it. A sound match reads the two charts side by side: each person’s main chart and Navamsa (the ninth-part chart read for marriage), the timing of their planetary periods, how the two charts connect, both Manglik checks, and the traditional 36-point guna score as one layer among the rest. No single score, Manglik or guna, settles a match.

For two people, the free compatibility check reads both charts layer by layer, with both Manglik checks and the both-partners rule.
