According to the U.S. Census Bureau, the population of people aged 90 and older has more than tripled in recent decades, highlighting a growing interest in this incredible life stage. When considering what do they call 90 year olds, the answer goes beyond simple phrases to reveal a rich vocabulary of aging.

Quick Summary

A person between 90 and 99 years old is formally known as a nonagenarian, a term derived from Latin. This specific title differentiates them from other age brackets, such as octogenarians (80s) and centenarians (100+).

Key Points

  • Nonagenarian: A person in their 90s (specifically, ages 90 through 99) is called a nonagenarian, a term rooted in Latin.

  • Etymological Context: The term is part of a series of decade-specific labels, including septuagenarian (70s), octogenarian (80s), and centenarian (100s).

  • Formal vs. Informal Usage: While "nonagenarian" is a formal term, common and respectful language like "senior" or "elder" is often used in casual conversation.

  • Longevity is Increasing: The population of people aged 90 and older is one of the fastest-growing demographics in the US, thanks to advancements in healthcare and lifestyle.

  • Thriving in Later Life: Many nonagenarians remain highly active and engaged, challenging old stereotypes of aging and highlighting the importance of a positive mindset and social connection.

  • Resilience and Adaptation: Research suggests that resilience, strong social support, and the ability to adapt to physical changes are key factors for a high quality of life in advanced years.

Understanding the Terminology of Aging

The word for a person in their 90s is nonagenarian. This term, while formal, is used to denote an individual who is between 90 and 99 years of age. It's part of a broader system of Latin-derived terms used to classify people by their decade of life, recognizing the significant milestones of long life.

The Latin Roots: Decoding the Decades

The suffix “-arian” comes from the Latin -arius, meaning “one that is concerned with.” By combining this with Latin prefixes for numbers, we get terms for each decade of adulthood:

  • Sexagenarian: 60s
  • Septuagenarian: 70s
  • Octogenarian: 80s
  • Nonagenarian: 90s
  • Centenarian: 100s
  • Supercentenarian: 110+

This classification provides a precise way to refer to individuals in their advanced years, particularly in medical, academic, and journalistic contexts. For everyday conversation, more casual terms like “senior,” “elder,” or simply “90-year-old” are common.

Life as a Nonagenarian: More than a Label

Reaching one's nineties is a remarkable achievement. Life at this stage is often characterized by a rich history of experiences, memories, and personal wisdom. It's a time that can bring unique challenges, but also immense joy and gratitude.

Many nonagenarians remain active and engaged with their families and communities. While physical health may require more attention, advancements in medicine and technology, along with improved nutrition and lifestyle, have helped extend both the lifespan and healthspan of many individuals. The concept of healthy aging, which includes physical activity, mental stimulation, and strong social connections, is particularly relevant for this age group.

Insights from the Centenarian Study

Research into centenarians and near-centenarians provides fascinating insights into the secrets of longevity. The New England Centenarian Study, led by Dr. Thomas Perls, has found that many of those who live to 90 and beyond share certain characteristics. These include a high degree of resilience, the ability to cope with stress, and strong social support systems.

The study suggests that while genetics play a role, lifestyle factors and a positive outlook are crucial for not only living a long time but living a high-quality life in advanced years. This highlights that being a nonagenarian is not just about survival, but about thriving.

The Importance of Respectful Language

When referring to people in their nineties, using respectful and positive language is paramount. Terms like "senior" or "elder" are widely accepted, but it's always best to consider the individual. Rather than focusing solely on age, focusing on a person's accomplishments, wisdom, and life story can be more meaningful.

Avoid using language that stigmatizes or marginalizes older adults, such as "the elderly" in a dismissive tone. Instead, embrace the idea that every decade of life is valuable and offers unique perspectives. This approach aligns with a modern view of aging that emphasizes dignity, respect, and continued contribution.

A Comparison of Decades: Nonagenarian vs. Octogenarian

Feature Octogenarian (80-89) Nonagenarian (90-99)
Etymology Latin for "eighty" (octoginta) Latin for "ninety" (nonaginta)
Common Characteristics May be highly active, recently retired, or still working. Often experiencing changes in mobility or health but maintaining independence. Represents a unique longevity milestone. Often involves greater reliance on support but may be exceptionally healthy.
Social Significance Seen as a traditional "senior" stage. Represents extreme longevity, often garnering significant respect and interest.
Health Focus Managing chronic conditions, maintaining activity levels, and planning for later life. Focusing on quality of life, preserving cognitive function, and adapting to physical changes.

The Rising Number of Nonagenarians

As healthcare and nutrition continue to improve, the number of individuals reaching their nineties is steadily increasing. The United States Census Bureau reports that the 90-and-older population is one of the fastest-growing segments of the U.S. population. This demographic shift has significant implications for everything from healthcare and senior care services to community design and social programs.

With more people living longer, there is a greater need for services that support older adults in maintaining their independence and well-being. This includes a focus on accessible housing, specialized medical care, and programs that combat social isolation.

Conclusion: Celebrating a Long Life

Understanding what they call 90 year olds is more than just a vocabulary lesson; it's an acknowledgment of a significant milestone in a person's life. The term nonagenarian honors a period of advanced age that fewer people have the privilege of experiencing. As society continues to navigate the implications of increased longevity, it's essential to celebrate and support this remarkable population segment, ensuring they can live with dignity, purpose, and respect.
