Determine the gender of a name

Namsor's name checking tool can help you determine if a name is more likely to be male or female. We offer many possibilities of treatments for gender name determination. Our technology supports a large number of alphabets*.

Genderize a first or split name
Determines the gender from a first name or a combination of a first name and a last name. Accuracy can be improved by adding a country of residence.
Genderize an unsplit full name
Determines the gender from a full name. Useful if unable to identify the structure of a name (first name/last name). Accuracy can be improved by adding a country of residence.
Genderize a Japanese name
Determines with greater precision the gender of a Japanese given name or a Japanese full name written in Latin alphabet or in Japanese characters (Kanji).
Genderize a Chinese name
Determines with greater precision the gender of a Chinese given name or a Chinese full name written in Latin alphabet (Pinyin) or in standard Mandarin Chinese.

From a first name and (last name) estimate the most likely gender

What is the gender of a name

Gender is a social construct that defines a set of characteristics considered to be linked to femininity and masculinity. Depending on some contexts, this may include identity, social, cultural, historical, political, and symbolic dimensions of gendered identities. Most cultures use a gender binary, in which gender is divided into two categories: boys/men/male and girls/women/female.


When it comes to assessing gender based on a full name or given name, it is important to point out that this does not guarantee absolute certainty, as some given names are commonly used by both genders, although in different proportions. Therefore, we provide an estimate of the probability of correctness of the identified gender. By adding a family name and/or a country of residence, the precision improves considerably, because it allows to better contextualize the use of the first name in its environment. When the probability of the identified gender is between 45% and 55%, this indicates that the name can be interpreted as not being specific to a particular gender.


For example, the name Keith Haring is identified as a male name with a probability of 90.63%.

From a full name estimate the most likely gender

Analyzes a unsplit full name (first name and surname) to identify the most likely gender. Indicate a country of residence to improve the accuracy of the determined gender. If the first name and surname are clearly identifiable, the Genderize Name feature will be slightly more accurate.

Gender: full name

Gender from an unsplit full name:

Unsplit full name (first name and last name).

From a Japanese name estimate the most likely gender

Analyzes a Japanese given name and optional surname, or an unsplit Japanese full name, in Kanji characters or Latin alphabet, to identify the most likely gender with higher accuracy. If the given name and surname are clearly identifiable, the GIVEN NAME & SURNAME variant will be slightly more accurate.

Gender: Japanese given name & surname

Gender from a Japanese given name an optional last name for more precision:

Japanese given name (first name) in Latin or Kanji characters.

Japanese surname (family name) in Latin or Kanji characters.

What is the gender of a Japanese name in Kanji or romanized

The gender of a Japanese name written in kanji or in Latin is an estimate based on a binary gender classification: masculine or feminine. In addition to being identified as predominantly masculine or feminine, a given name may qualify as unisex or gender-neutral if the probability of the estimated gender is close to 50%.

  • Kanji are the adopted logographic Japanese characters that are used in the Japanese writing system. Kanji is one of the three writing systems that are more commonly know as Japanese characters.
  • Romanization is the transcription or conversion of a different writing system using the Latin alphabet.

    For example, the combination of the Japanese given name 中松 and the Japanese last name 義郎 written in Kanji, is identified as a male name with a probability of 55.01%.

From a Chinese name estimate the most likely gender

Analyzes a Chinese given name and optional surname, or an unsplit Chinese full name, in standard Mandarin Chinese or in Latin alphabet (Pinyin), to identify the most likely gender with higher accuracy. If the given name and surname are clearly identifiable, the GIVEN NAME & SURNAME variant will be slightly more accurate.

information

The Genderize Chinese Full Name feature will only work with Chinese full names written in standard Mandarin Chinese.

Gender: Chinese given name & surname

Gender from a Chinese given name and an optional last name for more precision:

Chinese given name (first name) in Pinyin or standard Mandarin Chinese.

Chinese surname (last name) in Pinyin or standard Mandarin Chinese.

What is the gender of a Chinese name in standard Mandarin or Pinyin

The gender of a Chinese name written in standard Mandarin or in Pinyin is a binary classification of gender: masculine or feminine. If the probability of the returned gender is between 45% and 55%, the name can be interpreted as being a gender neutral (unisex) name.

  • Standard Mandarin Chinese is the official language of China. It uses a logographic system called Hanzi that is more commonly know as Chinese characters.
  • Pinyin is the official romanization system for Standard Mandarin Chinese. It is used to depict Mandarin logograms with the Latin alphabet, used by languages such as English.

    For example, the Chinese full name written in standard Mandarin Chinese 谢晓亮 is identified as a male name with a probability of 53.29%. This full name can be considered a unisex name because it is worn by almost as many men as women.
