Demographic profile in the context of "Serial killer"

In marketing, market segmentation or customer segmentation is the process of dividing a consumer or business market into meaningful sub-groups of current or potential customers (or consumers) known as segments. Its purpose is to identify profitable and growing segments that a company can target with distinct marketing strategies.

In dividing or segmenting markets, researchers typically look for common characteristics such as shared needs, common interests, similar lifestyles, or even similar demographic profiles. The overall aim of segmentation is to identify high-yield segments – that is, those segments that are likely to be the most profitable or that have growth potential – so that these can be selected for special attention (i.e. become target markets). Many different ways to segment a market have been identified. Business-to-business (B2B) sellers might segment the market into different types of businesses or countries, while business-to-consumer (B2C) sellers might segment the market into demographic segments, such as lifestyle, behavior, or socioeconomic status.

Indian Singaporeans are Singaporeans of Indian or broader South Asian ancestry. As of the 2020 census, they constitute approximately 9.0% of the country's residents, representing the third largest ethnic group in Singapore. In Singapore, "Indian" is an umbrella term defined in both geographical and ethnic-cultural contexts as pertaining to South Asia and bears no necessary relation to the contemporary Republic of India. Some Singaporeans of South Asian ancestry would simply just consider themselves "Singaporean", viewing themselves as distinct from the "India Indians" in terms of culture, identity and social reality.

The historical presence of ancient India influenced the indigenous Malay culture long before the founding of modern Singapore by the British Empire in 1819. Early Indian settlement was largely transient, composed primarily of male workers and soldiers. By the mid-20th century, however, the community had become more established, exhibiting a balanced gender ratio and a diversified age distribution. This period marked the emergence of a cohesive Indian Singaporean identity within the evolving social fabric of the island.

Singaporean Chinese or Chinese Singaporeans (simplified Chinese: 新加坡华人/华裔新加坡人; traditional Chinese: 新加坡華人/華裔新加坡人; pinyin: Xīnjiāpō Huárén / Huáyì Xīnjiāpōrén) are Singaporeans of Han ancestry. As of the 2020 census, they constitute 75.9% of the resident population, making them the largest ethnic group in Singapore. In Singapore, "Chinese" is an umbrella term defined in both geographical and ethnic-cultural contexts as pertaining to Greater China and bears no necessary relation to the contemporary People's Republic of China, whose citizens are classified separately when in Singapore. As a result, some Singaporeans of Han ancestry would simply just consider themselves "Singaporean", viewing themselves as distinct from the "China Chinese" in terms of culture, identity and social reality.

Evidence of Chinese people trading with and settling among local populations in Singapore dates as early as the 10th century. Prior to the establishment of Singapore as a British trading port, the island was home to a small community of around 120 Malays and 20 to 30 Chinese, mostly traders. The colonial period saw a substantial influx of male Chinese migrants, who often returned to their families in China after earning sufficient income. Over time, more ethnic Chinese arrived in Singapore such as the samsui women and other economic migrants. This led to a more balanced gender ratio and a diversified age distribution, which formed the bulk of the Singaporean Chinese population known today.

This list of lesbian, gay, bisexual, transgender and queer (LGBTQ) firsts by year denotes pioneering LGBTQ endeavors organized chronologically. Openly LGBTQ people remain a demographic minority in most places. In areas that historically are not known for having (or being friendly to) LGBTQ people who do not remain closeted, a "first" can make it easier for other openly LGBTQ persons to enter the field or for those who are closeted to come out. Openly LGBTQ people being visible in society affects societal attitudes toward homosexuality, bisexuality, and the transgender community on a wider level.

One commonly cited example is Michael McConnell and Jack Baker, the first openly gay couple to apply for a marriage license in 1971. Another is Harvey Milk, the first openly gay person to be elected to political office in California, becoming the most visible LGBTQ politician in the world in the 1970s, after decades of resistance to LGBTQ people by mainstream culture. Milk encouraged LGBTQ people to "come out of the closet" during his speeches; as a result of his work and his assassination—along with San Francisco mayor George Moscone—thousands of ordinary people did so. In 2002, Milk was called "the most famous and most significantly open LGBT official ever elected in the United States".

In medicine, a case report is a detailed report of the symptoms, signs, diagnosis, treatment, and follow-up of an individual patient. Case reports may contain a demographic profile of the patient, but usually describe an unusual or novel occurrence. Some case reports also contain a literature review of other reported cases. Case reports are professional narratives that provide feedback on clinical practice guidelines and offer a framework for early signals of effectiveness, adverse events, and cost. They can be shared for medical, scientific, or educational purposes.
