1991 is a Yin Metal Goat year in the Chinese sexagenary cycle. The full designation is Xin Wei (辛未): Xin is the Heavenly Stem and Wei is the Earthly Branch, and the branch is what people are actually naming when they say "the year of the goat".
Two people born twelve years apart share an animal but not a year. 1991 is Xin Wei: stem Xin (Metal) over branch Wei (Goat). Twelve years earlier or later the branch would repeat while the stem moved on, producing a Goat of a different element. The animal is the headline; the stem is what makes it specific.
In the Chinese zodiac the Goat is calm, gentle and creative, and its branch element is Earth. This is the layer most people are asking about when they ask what a 1991 birth means. The full Goat profile covers the temperament on its own; the elements below are what make 1991 specific.
A Metal stem year puts the emphasis on structure, standards and precision. These years produce people with a strong internal sense of how a thing should be done, and a correspondingly low tolerance for work that is merely good enough. Metal cuts away what is not needed, which is an asset professionally and, applied to people, can come across as coldness.
Yin years carry the receptive, inward expression of the same element. The stem sits in its "shaded" phase, which shows up as a preference for timing — you would rather wait for the right moment than force the wrong one.
Taken together, 1991 produces a personality that reads as calm, gentle and creative to the outside and runs on metal logic underneath. In practice that means the Goat description you have read elsewhere is accurate but incomplete — it describes the visible layer, and the stem explains why you do not always behave like a textbook Goat.
Born in the 1990s, you grew up with the internet already present and had to learn its rules as they were being written.
Love and partnership in a Xin Wei year run on two clocks. The Goat layer wants calm and gentle and creative; the metal stem adds a need for clear terms and kept promises.

Applied to work, the Goat contribution is calm, gentle and creative, which means you are usually the person who quietly holds the standard while others get distracted.
1991 is the year of the Goat — Xin Wei (辛未), combining the stem Xin (Metal) with the branch Wei (Goat). In the common shorthand it is called a Yin Metal Goat year.
1991 carries two elements in two different systems. The Heavenly Stem Xin is Metal, which is the one people usually mean when they ask about the element of a birth year. The Earthly Branch Wei belongs to Earth in the twelve-branch system. The stem element leads; the branch element modifies it.
The sixty-year cycle means the exact combination of stem, branch and element repeats every sixty years. 1931 and 2051 are the same Yin Metal Goat year. The animal alone returns every twelve years, but with a different stem and therefore a different element.
No. The birth year is one layer of the Chinese system, alongside the month (the inner animal), the day and the hour. Popular usage collapses all of it into the birth-year animal because that is the part everyone knows. Treat the reading here as one accurate layer rather than a complete chart — it is specific, but it is not the whole picture.
Every sign. A calendar year contains all twelve sun signs, so "what sign were 1991 babies" has twelve answers depending on the birth date. 1991 began on a Tuesday and had 365 days. If you want the Western side, use the birthday pages instead — this page covers the Chinese birth-year layer, which is the one that does narrow to a single answer.
