Health literacy relates to how people access, understand and use health information in ways that benefit their health. People with low health literacy are at higher risk of worse health outcomes and poorer health behaviours.
The idea of health literacy is dynamic and evolving. While there are many published definitions, there is no consensus on its meaning (Sørensen et al. 2012). Health literacy initially focused on the ability of individuals to read and understand medical information, however the way information is delivered by health care professionals and organisations is equally important. Therefore, health literacy has 2 main components:
People with low health literacy are more likely to have worse health outcomes overall (Berkman et al. 2011) and adverse health behaviours, such as:
In contrast, better levels of health literacy are associated with increased patient involvement in shared decision making (de Oliveira et al. 2018; Seo et al. 2016), which is important in patient-centred care. Improving health literacy is therefore a key element in allowing people to partner with health professionals for better health.
At the population level, low health literacy may be a contributing factor to health inequalities among certain groups (Kickbusch et al. 2006). There is a strong association between some social determinants of health, such as lower levels of education and socioeconomic status, older age, and being from a culturally and linguistically diverse background, and low health literacy (Adams et al. 2009; Heijmans et al. 2015; Rowlands et al. 2015). Targeting health literacy programs at these groups has the potential to reduce health inequalities.
The COVID-19 pandemic highlights the importance of health literacy in the wider community, as whole populations are asked to understand and rapidly digest complex health concepts relating to infection, immunity and use of the health care system—for example, ‘flattening the curve’—to produce a coordinated response to try and slow the spread of disease. Understanding health literacy levels among the population (and vulnerable sub-populations) helps the development and delivery of consumable and effective population health messages during such large-scale outbreaks.

Data generated by measuring health literacy can inform policy decisions and assist health organisations to tailor services appropriately to particular groups of people. The Organisation for Economic Co-operation and Development (OECD) identified that addressing gaps in health literacy measurement is an important way to remove barriers to health literacy (Moreira 2018). However, the ability to measure health literacy is hampered by the broad range of definitions, a lack of consensus on what to measure, and the multiple approaches to measuring it (Osborne et al. 2013; Poureslami et al. 2017). This makes it difficult to provide comparable reporting on health literacy over time.
In 2018, the Australian Bureau of Statistics (ABS) conducted the Health Literacy Survey (ABS 2019), using the Health Literacy Questionnaire (HLQ) (Osborne et al. 2013). The HLQ is a validated tool that has been used in a range of settings, in Australia and abroad (ABS 2019; Bo et al. 2014; NZ Ministry of Health 2018).
The benefits of the Health Literacy Survey data are that they report a larger range of health literacy characteristics and can therefore be used to improve health service provision. The HLQ does not give a total score of health literacy, nor does it state whether health literacy levels are high or low. Rather, it assesses health literacy across 9 domains that encompass both individual and health environment measures and so provides information about gaps or strengths in the health literacy of the population (Beauchamp et al. 2017).
Selected estimates from the ABS Health Literacy Survey are:
This chart shows that there were some minor differences in the proportion of persons who found it easy to engage with healthcare providers. In general, older persons were more likely to always find it easy to actively engage with healthcare providers (38.7% of those aged 65 and older, and 37.7% of those aged 55-64). Only 26.5% of those aged 35-44 and 27.7% of those aged 18-24 always find it easy to actively engage with healthcare providers. Additionally, those who spoke English in the home were more likely to always find it easy to actively engage with healthcare providers (33.7%) than those who spoke a language other than English in the home (25.8%).
Figure 1a data table (130KB XLSX)
This chart shows the proportion of persons who agreed that they feel understood and supported by healthcare providers varied by age group and by language spoken in the home. Those aged 65 and over had the highest proportion of persons who agreed or strongly agreed that they feel supported by healthcare providers (98.1%) and those aged 35-44 had the lowest proportion (93.1%). Overall, the proportion of persons who disagreed or strongly disagreed that they feel understood and supported by healthcare providers was similar for persons who spoke English in the home (4.2%) and those who did not (5.2%). However, persons who spoke English in the home had a higher proportion who strongly agreed they feel understood and supported by healthcare providers (33%) than those who did not speak English in the home (20%).
Figure 1b data table (130KB XLSX)
The findings from the ABS Health Literacy Survey also showed that for some domains there was variation by age group. Younger people aged 18–24 were almost twice as likely to strongly agree that they have access to social support compared with older people aged 65 and over (39% compared with 20%). In contrast, navigating the health care system appears to be more difficult for younger age groups. Nearly 1 in 5 (19%) people aged 18–24 stated that they found navigating the health care system difficult, and this decreased to 7.9% for those aged 65 and over.
There was also some variation in the results according to main language spoken in the home (figures 1a and 1b). Overall, the proportion of people who disagreed or strongly disagreed that they feel understood and supported by health care providers was similar for people who spoke English in the home (4.2%) and those who did not (5.2%). However, a higher proportion of people who spoke English in the home strongly agreed they feel understood and supported by health care providers (33%) than those who did not speak English in the home (20%).
Additionally, those who spoke English in the home were more likely to always find it easy to actively engage with health care providers (34%) than those who spoke a language other than English in the home (26%).
The National Statement on Health Literacy (ACSQHC 2014b) acknowledges the importance of health literacy in enabling effective partnerships in health, and proposes actions that can be implemented within the health system to improve health literacy levels. This has been a driver for health literacy at the local level, with Local Health Networks, Primary Health Networks and community organisations designing and implementing locally appropriate health literacy interventions.
Some examples of activities being undertaken at the national and community levels to improve health literacy are provided below.
The National Strategic Framework for Chronic Conditions (Australian Health Ministers’ Advisory Council 2017) and the National Safety and Quality Health Service Standards (ACSQHC 2017) are 2 national initiatives that acknowledge and integrate health literacy as an important component of the health system.
The Centre for Culture, Ethnicity and Health works closely with community, government and health professionals to represent people from culturally diverse backgrounds, particularly migrants and refugees. It provides a range of resources to address health literacy across all audiences, including:
