Surveying the Ageing Population



As life expectancy continues to increase and birth rates decline, the world's population is growing older at an unprecedented rate. By 2050, it is estimated that one in five people will be over the age of 65. This demographic shift has far-reaching consequences for society, including health, social services, and the economy. To better understand the needs and experiences of the ageing population, surveying is a crucial tool.

Why survey the ageing population?

Surveys of the ageing population provide valuable insights into the health, well-being, and attitudes of this demographic. They help policymakers and researchers to identify the specific needs and challenges faced by older people and to develop targeted interventions that address these issues.

In addition to informing policy, surveys can also help to improve services for the ageing population. For example, surveys can be used to assess the quality of healthcare and social services for older people and to identify areas for improvement. Surveys can also provide information about the use of technology by older people, including the adoption of new technologies and the barriers to their use.

Designing a survey for the ageing population

When designing a survey for the ageing population, it is important to consider the following factors:

  • Response rate: Older people may be less likely to respond to surveys due to physical or cognitive limitations. Therefore, it is important to design a survey that is easy to complete and accessible to all.

  • Question format: Questions should be simple and straightforward, with clear instructions for answering. Avoid complex questions and technical language that may confuse older respondents.

  • Mode of delivery: Surveys can be delivered in a variety of ways, including by mail, phone, or online. It is important to consider the preferred mode of delivery for older people, taking into account factors such as accessibility and technological proficiency.

  • Privacy and confidentiality: Older people may be concerned about privacy and confidentiality when responding to surveys. It is important to ensure that survey responses are anonymous and that personal information is protected.

How to increase response rates to surveys of older people?

High Contrast Colors

To ensure that surveys are accessible to all individuals, it is important to use high contrast colors. High contrast color combinations, such as black text on a white background, make it easier for participants with visual impairments to distinguish between different elements in the survey. This helps to increase the visibility of questions and answers and makes the survey easier to read. Avoid using light or low contrast color combinations, such as yellow on a light green background, as they can be difficult to distinguish, especially for people with limited vision.

Large Font Sizes

The font size used in the survey should be large enough to be easily read by all participants. A minimum font size of 19 pixels (14 points) is recommended to ensure readability, especially for seniors. Smaller font sizes can make the survey difficult to read, causing frustration and reducing response rates. It is important to consider that as people age, their eyesight may deteriorate, making it necessary to use larger font sizes.

Simple Font Styles

The font style used in the survey should be simple and easy to read. Avoid using complex or ornate fonts, as they can be challenging for seniors to read. Choosing a font that is legible and commonly used will help to increase the response rate of the survey. A font style that is commonly used, such as Arial or Times New Roman, is a good choice as it will be familiar to participants and easy to read.

Additional Tips

To increase response rates to surveys of older individuals, it is important to consider the needs and preferences of this demographic. In addition to using high contrast colors, large font sizes, and simple font styles, other strategies that can be employed include:

  • Providing clear and simple instructions for completion, including instructions on how to skip questions if necessary.

  • Ensuring privacy and confidentiality, by using secure data collection methods and communicating this to participants.

  • Providing support and assistance, such as having someone available to answer questions and assist with the completion of the survey.

  • Following up with non-responders, either by sending a reminder letter or making a follow-up phone call.

By using these strategies, it is possible to increase response rates to surveys of older individuals, providing valuable insights into the needs and experiences of this demographic.


As the world's population grows older, surveying the ageing population is becoming increasingly important. Surveys provide valuable insights into the health, well-being, and attitudes of older people and inform the development of policies and services that address the needs of this demographic. By considering the unique needs and characteristics of older people, it is possible to design surveys that accurately represent the ageing population and provide meaningful insights.
