The catalogue, counted
Every figure here is a count over the whole catalogue, not a sample. Two of them are worth staying for: rising signs are not evenly distributed and should not be, and the recorded birth times are rounded far more heavily than anyone quoting them tends to say.

Births from 770 BCE to 2026. A further 35,594 people carry a rating but no clock time — the record says explicitly that the hour is unknown, which is worth more than a guess.
Births per century. The shape is the record's, not history's: it reflects who has been written down and digitised, which is overwhelmingly the recent and the European.
Rising signs
Leo rises 2.4 times as often as Pisces across the 37,224 charts that have an Ascendant. That is not a flaw in the data. The ecliptic meets the horizon at a different angle for each sign, so at northern latitudes some signs take well over two hours to clear the horizon and others little more than an hour — the signs of long and short ascension. A catalogue drawn mostly from the northern hemisphere should look exactly like this, and one that came out flat would be the suspicious one.
Bars run from an even twelfth (8.33%, the centre rule) to either side; the last column is the miss in percentage points.
Sun signs
Nearly even, with a seasonal wobble of about a percentage point — more people are born in some months than others, and that is the whole of the effect. All 1,768,650 people have one, because a date alone fixes the Sun.
Moon signs
The flattest of the three. The Moon crosses a sign in about two and a half days, so its distribution washes out any seasonal pattern almost completely — 37,224 charts, and the spread from most to least common is under 0.49 points.
How the times were written down
Of the 39,984 recorded clock times, 36.3% fall exactly on the hour and 84.2% on a multiple of five. If births were recorded to the minute, those figures would be 1.7% and 20%. What you are looking at is people rounding — and an Ascendant moves roughly a degree every four minutes, so a time rounded to the nearest half hour can carry the Ascendant several degrees, and across a cusp.
Minute of the hour. The dashed line is where every bar would sit if times were recorded to the minute — 666 each. The bar at :00 is 22 times that.

Most recorded occupations
Counts recomputed from the roster whenever it changes on disk. Sign placements come from the derived index, which is rebuilt from computed positions rather than stored with the roster.
