Measurement of child labour prevalence has evolved considerably over the past two decades. Estimates of child labour incidence are more robust and exist for more countries than any other form of exploitation falling under SDG Target 8.7.

No nationally representative data is available on child labour prevalence in Tonga.

Visit the How to Measure the Change page for information on ILO-SIMPOC methods and guidelines for defining, measuring and collecting data on child labour.

Measuring the incidence of forced labour is a much more recent endeavour and presents unique methodological challenges compared to the measurement of child labour.

No nationally representative data is available on forced labour prevalence in Tonga.

Visit the How to Measure the Change page for information on new guidelines presented by the International Labour Organization and adopted by the International Conference of Labour Statisticians.

The challenges in estimating human trafficking are similar to those of estimating forced labour, though recent innovations in estimation have begun to produce prevalence estimates in developed countries.

No nationally representative data is available on human trafficking prevalence in Tonga.

Visit the How to Measure the Change page to learn about measuring human trafficking prevalence, including information on collecting data through national referral mechanisms and producing prevalence statistics using Multiple Systems Estimation (MSE).

Case Data: International and Non-Governmental Organizations

Civil society organizations (CSOs) focused on human trafficking victim assistance can serve as crucial sources of data given their ability to reach a population that is notoriously difficult to sample.

Counter Trafficking Data Collaborative (CTDC): The International Organization for Migration (IOM), Polaris and Liberty Asia have launched a global data repository on human trafficking, with data contributed by counter-trafficking partner organizations around the world. Not only does the CTDC serve as a central repository for this critical information, it also publishes normed and harmonized data from various organizations using a unified schema. This global dataset facilitates an unparalleled level of cross-border, trans-agency analysis and provides the counter-trafficking movement with a deeper understanding of this complex issue. Equipped with this information, decision makers will be empowered to create more targeted and effective intervention strategies.

Prosecution Data

UNODC compiles a global dataset on detected and prosecuted traffickers, which serves as the basis in their Global Report for country profiles. This information is beginning to paint a picture of trends over time, and case-specific information can assist investigators and prosecutors.

Key aspects of human development, such as poverty and lack of education, are found to be associated with risk of exploitation. Policies that address these issues may indirectly contribute to getting us closer to achieving Target 8.7.

Human Development Index (Source: UNDP)

The Human Development Index (HDI) is a summary measure of achievements in three key dimensions of human development: (1) a long and healthy life; (2) access to knowledge; and (3) a decent standard of living. Human development can factor into issues of severe labour exploitation in multiple ways.

The chart displays information on human development in Tonga between 1990 and 2018. Only certain sample years have data disaggregated by sex. 

The most recent year of the HDI, 2018, shows that the average human development score in Tonga is 0.717. This score indicates that human development is high. 


HDI Education Index (Source: UNDP)

Lack of education and illiteracy are key factors that make both children and adults more vulnerable to exploitive labour conditions.

As the seminal ILO report Profits and Poverty explains:

“Adults with low education levels and children whose parents are not educated are at higher risk of forced labour. Low education levels and illiteracy reduce employment options for workers and often force them to accept work under poor conditions. Furthermore, individuals who can read contracts may be in a better position to recognize situations that could lead to exploitation and coercion.”

The bars on the chart represent the Education Index score and the line traces the mean years of education in Tonga over time.


Decent work, a major component of SDG 8 overall, has clear implications on the forms of exploitation within Target 8.7. Identifying shortcomings in the availability of equitable, safe and stable employment can be a step in the right direction towards achieving Target 8.7.

HDI Vulnerable Employment (Source: UNDP)

There are reasons to believe that certain types of labour and labour arrangements are more likely to lead to labour exploitation. According to the ILO:

“Own-account workers and contributing family workers have a lower likelihood of having formal work arrangements, and are therefore more likely to lack elements associated with decent employment, such as adequate social security and a voice at work. The two statuses are summed to create a classification of ‘vulnerable employment’, while wage and salaried workers together with employers constitute ‘non-vulnerable employment’.”

Between 1991 and 2018, Tonga showed a decrease in the proportion of workers in vulnerable employment as compared to those in secure employment.


Labour Productivity (Source: ILO)

Labour productivity is an important economic indicator that is closely linked to economic growth, competitiveness, and living standards within an economy.” However, when increased labour output does not produce rising wages, this can point to increasing inequality. As indicated by a recent ILO report (2015), there is a “growing disconnect between wages and productivity growth, in both developed and emerging economies”. The lack of decent work available increases vulnerability to situations of labour exploitation. 

Labour productivity represents the total volume of output (measured in terms of Gross Domestic Product, GDP) produced per unit of labour (measured in terms of the number of employed persons) during a given period.


Research to date suggests that a major factor in vulnerability to labour exploitation is broader social vulnerability, marginalization or exclusion.


Achieving SDG Target 8.7 will require national governments to take direct action against the forms of exploitation through policy implementation.

Governments can take action to assist victims and to prevent and end the  perpetration of forced labour, modern slavery, human trafficking and child labour. These actions should be considered in wider societal efforts to reduce prevalence and move towards eradication of these forms of exploitation.

Measures to address the drivers of vulnerability to exploitation can be key to effective prevention. A broad range of social protections are thought to reduce the likelihood that an individual will be at risk of exploitation, especially when coverage of those protections extends to the most vulnerable groups.

Social Protection Coverage: General (at Least One)
Social Protection (Source: ILO)

The seminal ILO paper on the economics of forced labour, Profits and Poverty, explains the hypothesis that social protection can mitigate the risks that arise when a household is vulnerable to sudden income shocks, helping to prevent labour exploitation. It also suggests that access to education and skills training can enhance the bargaining power of workers and prevent children in particular from becoming victims of forced labour. Measures to promote social inclusion and address discrimination against women and girls may also go a long way towards preventing forced labour.

If a country does not appear on a chart, this indicates that there is no recent data available for the particular social protection visualized.
