There is no single agreed‑upon number of “races,” and many scientists today argue that the concept of race itself is not biologically meaningful but a social construct.

Short, direct answer

  • Historically, scholars often spoke of 3–5 “major races” (for example: Caucasian, Mongoloid/Asian, Negroid/Black, and sometimes Australoid or others).
  • Modern genetics shows humans are 99.9%+ genetically alike , and clear biological race boundaries do not exist.
  • Because of this, many experts and institutions now prefer talking about ethnic groups or populations rather than races, and there are thousands of such groups worldwide.

What “race” used to mean

For much of the 19th and 20th centuries, anthropologists tried to sort humans into a few “major races.” A common scheme talked about:

  1. Caucasian (often mapped onto “white” people).
  1. Mongoloid or Asian (very broadly including East Asians, some Southeast Asians, Indigenous peoples of the Americas, etc.).
  1. Negroid or Black (broadly sub‑Saharan African and some other groups).
  1. Sometimes a fourth, Australoid (Aboriginal Australians and some Pacific groups).

Even within those schemes, people acknowledged you could subdivide these into dozens of subgroups (around 30 or more), based on geography and appearance.

Why modern science says “it’s not that simple”

Genetic research has shown that humans are extremely similar at the DNA level: our genomes are more than 99.99% the same , no matter what “race” we are assigned. This means:

  • There is more variation within any so‑called race than between races.
  • Boundaries like “Black/White/Asian” do not map cleanly onto genetics or clear biological clusters.

Because of this, many organizations and scholars say race is better understood as a social construct —a way societies historically categorized people, often linked to power, inequality, and discrimination.

A popular example from forums and discussions is that depending on which country you’re in, the same person might be labeled a different “race,” which shows how flexible and social the labels are.

So how many “races” are there today?

Different answers exist because they are based on different social or historical systems, not on fixed biology:

  • Some old anthropological models: 3–4 major races (with many subgroups).
  • Some enthusiasts or amateur schemes online might list 8 or more “races” , based on geographic regions like “Central/North Asian,” “Sub‑Saharan African,” “Polynesian/Micronesian,” etc.
  • Some people argue there is just one human race , emphasizing our shared humanity.

In official forms (like censuses), each country builds its own categories, which might mix “race,” “ethnicity,” and even nationality (for example, separate boxes for “White,” “Black or African American,” “Asian,” “Native American,” “Hispanic/Latino,” etc.). These are administrative categories , not universal scientific races.

Ethnicity vs. race

Because “race” is so fuzzy, a lot of modern discussions focus on ethnicity instead:

  • An ethnic group usually means people who share culture, language, history, and identity , not just physical traits.
  • There are estimated to be over 5,000 ethnic groups in the world.

In many online forums, people point out that talking about the thousands of ethnicities is often more accurate and respectful than trying to force everyone into a handful of racial boxes.

Mini‑TL;DR

  • Old models: 3–4 major races, with many subgroups.
  • Modern science: human genetic differences are gradual, not neatly split into races; race is largely a social category.
  • Today, the most defensible answer is: there is one human species, thousands of ethnic groups, and no single correct number of “races.”
