What is the rarest Human Design type?

The Reflector is the rarest Human Design type. Measured across 40,000 computed charts, Reflectors are 0.95 percent, roughly one person in a hundred. The full distribution is Generator 36.1 percent, Manifesting Generator 31.9 percent, Projector 21.4 percent, Manifestor 9.6 percent and Reflector 0.95 percent. A Reflector has no defined centers at all, which is why the type is so uncommon.

What is the rarest Human Design profile?

The rarest profiles are the left angle and juxtaposition profiles. Measured across 40,000 charts, 2/5 and 5/2 are the rarest at 2.06 percent each, followed by 6/3 at 2.18 percent, 4/1 at 2.24 percent, 3/6 at 2.31 percent and 1/4 at 2.46 percent. The six right angle profiles are far more common, each between 14.2 and 14.8 percent. The reason is mechanical. Profile is the line of the Personality Sun paired with the line of the Design Sun, and the Design chart is taken at a fixed 88 degrees of solar arc before birth. That distance equals 93.87 lines, and since lines run in sixes the remainder is 2.13, so the Design Sun lands two lines ahead of the Personality Sun 86.7 percent of the time and three lines ahead 13.3 percent of the time. A two-line gap gives the six common profiles and a three-line gap gives the six rare ones.

What is the rarest Human Design authority?

Lunar authority is the rarest, at 0.95 percent, because only Reflectors have it. Among the rest, Ego authority is rarest at 1.43 percent, then Mental at 1.83 percent and Self-Projected at 2.58 percent. Emotional authority is by far the most common at 52.4 percent, followed by Sacral at 32 percent and Splenic at 8.9 percent.

What is the rarest Human Design gate?

There is no rare Human Design gate. Every gate occupies an equal 5.625 degree slice of the zodiac wheel, so all 64 gates are activated at a similar rate. Measured across 40,000 charts, the least common gate is gate 16 at 25.2 percent and the most common is gate 1 at 36.6 percent, a narrow spread caused by the uneven speeds of the planets rather than by any gate being rare. Any source naming a single rarest gate is not measuring anything.

How rare is it to have no definition in Human Design?

No Definition, meaning no defined centers at all, occurs in 0.95 percent of charts and belongs only to Reflectors. The rarest definition among people with defined centers is Quadruple Split at 0.71 percent. Split Definition is the most common at 47.6 percent, then Single at 38.6 percent and Triple Split at 12.1 percent.

Which Human Design center is least often defined?

The Head center is defined least often, in 28.3 percent of charts, followed by the Heart or Ego center at 37 percent and the Ajna at 48.1 percent. The Throat is defined most often at 68.7 percent, closely followed by the Sacral at 68 percent. An undefined center is where a person takes in and amplifies the energy of others.

What each type is built for, and how common each one actually is. The percentages here were measured by computing 40,000 charts.

Generator bodygraph with the Sacral centre defined and no motor connected to the Throat — Generator36.1% of chartsSacral defined, nothing driving the Throat

Manifesting Generator bodygraph with the Sacral defined and connected through to the Throat — Manifesting Generator31.9% of chartsSacral defined and a motor reaching the Throat

Projector bodygraph with definition but no Sacral and no motor reaching the Throat — Projector21.4% of chartsNo Sacral, no motor to the Throat

Manifestor bodygraph with a motor centre connected to the Throat and the Sacral open — Manifestor9.6% of chartsA motor to the Throat, Sacral open

Reflector bodygraph with all nine centres open and no channel complete — Reflector0.95% of chartsEvery centre open, no channel complete

Each bodygraph shows the minimum that defines the type. None of them is a particular person's chart. Coloured centres are defined, outlined ones are open.

The short answer

There are five Human Design types. Generators are the most common at 36.1%. Reflectors are the rarest at 0.95%, roughly one person in a hundred.

Type	How common	Strategy	Signature
Generator	36.1%	Respond	Satisfaction
Manifesting Generator	31.9%	Respond	Satisfaction
Projector	21.4%	Wait for the invitation	Success
Manifestor	9.6%	Inform	Peace
Reflector	0.95%	Wait a lunar cycle	Surprise

Your type is decided by which of the nine centers in your chart are defined, and how they connect. It is not a personality label. It describes how your energy is built to work, and therefore how decisions tend to go well or badly for you.

This page is the mechanics. The living part is in the app.

What is here is structure: what is defined, how common it is, what the numbers say. It is dry on purpose, because it is a reference.

How any of it actually shows up in a decision, a conversation or an ordinary week is not something a page can tell you. That is what Omni is for. Enter your birth data once and the chart becomes yours to work with.

Where these numbers come from

These statistics were produced by computing 40,000 complete bodygraphs, using the same engine that runs Omni Chart Reader, and counting the results. The birth moments were spread evenly across the years 1950 to 2025.

This measures the distribution of possible birth moments. A census of living people would come out slightly different, because real births are unevenly spread across the year. Most published percentages do not tell you which of the two they are.

The rarest type: Reflector, at 0.95%

A Reflector has no defined centers at all. Every one of the nine is open, which is why the type is so uncommon: it requires that none of the 26 planetary activations in a chart happens to complete a single channel.

Because nothing in a Reflector is fixed, they take in and amplify whatever is around them. That is why their strategy is to wait a full lunar cycle, about 28 days, before a major decision. It gives the sampling time to average out.

There is no rare gate, and this is measurable

A common question is which Human Design gate is rarest. The premise is wrong. Each of the 64 gates occupies an equal 5.625 degree slice of the wheel, so no gate can be rare in the way a type can.

Across the same 40,000 charts, the least activated gate is gate 16 at 25.2% and the most activated is gate 1 at 36.6%. That narrow spread comes from the planets moving at different speeds through different parts of the zodiac. No gate is scarce. Any page naming one single rarest gate is repeating something rather than measuring it.

Inner authority, measured

Authority is how your body signals a yes or a no. It is not the same as type, and it matters more day to day.

Authority	How common
Emotional	52.4%
Sacral	32.0%
Splenic	8.9%
Self-Projected	2.6%
Mental	1.8%
Ego	1.4%
Lunar	0.95%

Just over half of all charts carry Emotional authority, which means a defined Solar Plexus and a decision that should never be made on the spot. Lunar authority is rarest because only Reflectors have it.

Profile, and why six are common and six are not

Profile is the pair of roles you learn through. Six profiles appear roughly seven times more often than the other six.

Profile	How common
1/3	14.8%
6/2	14.6%
2/4	14.5%
5/1	14.3%
3/5	14.3%
4/6	14.2%
1/4	2.5%
3/6	2.3%
4/1	2.2%
6/3	2.2%
2/5	2.1%
5/2	2.1%

Why six profiles are common and six are not

This one has a clean mechanical answer, and it is rarely explained.

Your profile is two numbers: the line of your Personality Sun, and the line of your Design Sun. The Design chart is taken at a fixed distance before you were born: 88 degrees of solar arc, which works out to roughly 88 days.

Because that distance is fixed, the gap between the two lines is almost fixed too. Each line spans 0.9375 degrees of the wheel, so 88 degrees is 93.87 lines. Since lines run in sixes, what matters is the remainder: 2.13 lines.

So the Design Sun lands two lines ahead of the Personality Sun almost every time, and three lines ahead only when that leftover 0.13 tips it over. Measured across the sample, the gap is two lines in 86.7% of charts and three lines in 13.3%, which is that 0.13 remainder showing up exactly where you would expect it.

A two-line gap produces 1/3, 2/4, 3/5, 4/6, 5/1 and 6/2: the six common profiles. A three-line gap produces 1/4, 2/5, 3/6, 4/1, 5/2 and 6/3: the six uncommon ones. That is the whole reason. Nothing about the rarer profiles is special or more evolved. They are what happens when the Sun's own varying speed nudges the Design Sun one line further than usual.

Definition, measured

Definition	How common
Split	47.6%
Single	38.6%
Triple Split	12.1%
No Definition	0.95%
Quadruple Split	0.71%

Quadruple Split is the rarest definition anyone with defined centers can have, at 0.71%. No Definition belongs only to Reflectors.

Which centers are defined least often

The Head center is defined least often, in 28.3% of charts. The Throat is defined most often, in 68.7%.

Center	Defined in
Throat	68.7%
Sacral	68.0%
Root	60.7%
Spleen	58.3%
G	58.1%
Solar Plexus	52.4%
Ajna	48.1%
Heart	37.0%
Head	28.3%

An open center is not a weakness. Defined centers are consistent and reliable. Open centers are where you take in and amplify what other people are carrying, which is uncomfortable to live with and is also where most of your wisdom about people comes from.

Rarity is not rank

Being a rarer type does not mean being a better one. A Reflector is not more advanced than a Generator, and a 5/2 is not a superior 1/3. The percentages describe how the mechanics distribute, nothing more.

The useful question is whether you are living your design. Almost all of the practical value in Human Design sits in two things: your strategy, and your authority.
