The Social Institutions and Gender Index 2019 conceptual framework

The OECD Development Centre’s Social Institutions and Gender Index (SIGI) is a unique cross-country measure of discriminatory social institutions, encompassing formal and informal laws, social norms and practices that restrict women’s and girls’ rights, access to empowerment opportunities and resources. The SIGI consists of four components that provide policy makers with facts and evidence to enhance governments’ efforts to deliver on gender equality commitments (Box I).

Box I. The four SIGI components

• Country profiles contain comprehensive, qualitative information on legal frameworks and action plans to protect women’s rights and promote gender equality (for 180 countries).

• The Gender, Institutions and Development Database (GID-DB) comprises variables measuring the level of discrimination in laws (categorical variable), social norms (attitudinal data) and practices (prevalence rates) for 180 countries

• A cross-country ranking classifies 120 countries according to their level of discrimination in social institutions.

• A policy simulator allows policy makers to scope out reform options and assess their likely effects on gender equality in social institutions.

The SIGI focuses on gaps that legislation, attitudes and practices create between women’s and men’s rights and opportunities. The Index covers four dimensions spanning major socio-economic areas that affect women’s and girls’ entire lifetimes (Figure I):

• “Discrimination in the family” captures social institutions that limit women’s decision-making power and undervalue their status in the household and the family.

• “Restricted physical integrity” captures social institutions that increase women’s and girls’ vulnerability to multiple forms of violence and limit their control over their bodies and reproductive autonomy.

• “Restricted access to productive and financial resources” captures women’s restricted access to and control over critical productive and economic resources and assets.

  “Restricted civil liberties” captures discriminatory laws and practices restricting women’s access to and participation and voice in the public and social spheres.

Each dimension builds on four indicators combining qualitative and quantitative information. In theory, each indicator builds on a combination of three variables:

• Laws are discrete variables that are used to measure the level of discrimination in formal and informal laws.

• Attitudes and practices are continuous variables that are used to measure the level of discrimination in social norms.

In practice, the variables used as proxies for each indicator depend on data availability, reliability and country coverage. For example, some variables are not available at all (e.g. information on inheritance practices), while others are available only for a few countries (e.g. time spent on unpaid care work). Consequently, discrepancies exist between the theoretical framework and the variables included in the SIGI 2019. Overall, the SIGI framework builds on 27 core variables.

The SIGI 2019 is the fourth edition of the SIGI. For this edition, the conceptual framework was entirely revised, which renders comparison over time impossible at the aggregate level (index, dimensions and indicators). Nevertheless, some comparison over time is possible at the variable level for attitudes and practices. For more details on the SIGI methodology, refer to Annex B.

Geographical coverage

The data collection process for the fourth edition of the SIGI in 2019 covered 54 countries in Africa classified into five sub-regions (Table I).

Table I. Countries included in the SIGI analysis, by sub-regions
Central Africa	East Africa	North Africa	Southern Africa	West Africa
Burundi	Comoros	Algeria	Angola	Benin
Cameroon	Djibouti	Egypt	Botswana	Burkina Faso
Central African Republic	Eritrea	Libya	Eswatini	Cabo Verde
Chad	Ethiopia	Mauritania	Lesotho	Côte d'Ivoire
Democratic Republic of the Congo	Kenya	Morocco	Malawi	Gambia
Equatorial Guinea	Madagascar	Tunisia	Mozambique	Ghana
Gabon	Mauritius		Namibia	Guinea

Sao Tome and Principe	Seychelles		Zambia	Liberia
	Somalia		Zimbabwe	Mali
	South Sudan			Niger
	Sudan			Nigeria
	Uganda			Senegal
	Tanzania			Sierra Leone
				Togo

Only 31 African countries were given a SIGI score in 2019, due to data limitations and the fact that an overall SIGI score can be computed only for countries with data points in every single indicator and variable comprising the index (Figure II).

Note: The SIGI framework comprises a total of 4 dimensions and 16 indicators.

Conversely, 23 African countries lack sufficient data to compute scores across all 16 SIGI indicators (Table II). The most problematic variables from a data point of view are:

• The practice variable of the “Violence against women” indicator, which measures the share of women who have suffered intimate partner physical and/or sexual violence during their lifetime. Data for this variable are missing for 16 African countries.

• The practice variable of the “Access to financial services” indicator, which measures the share of women within the total population aged 15 years and over who have an account at a financial institution. Data for this variable are missing for 10 African countries.

• The attitude variable of the “Workplace rights” indicator, which measures the share of the population that disagrees with the statement: “It is perfectly acceptable for any woman in your family to have a paid job outside the home if she wants to”. Data for this variable are missing for 12 African countries.

• The practice variable of the “Workplace rights” indicator, which measures the share of women within the total population employed in management. Data for this variable are missing for 14 African countries.

• The practice variable of the “Freedom of movement” indicator, which measures the share of women within the total population who declare not feeling safe walking alone at night in the city or area where they live. Data for this variable are missing for 14 African countries.

• The practice variable of the “Access to justice” indicator, which measures the share of women within the total population who declare not having confidence in the judicial system and courts of their country. Data for this variable are missing for 15 African countries.

Timing and data sources

Qualitative data

The qualitative information for the 54 African country profiles was developed through a multiple-stage internal drafting and reviewing process. First, legal consultants responded to a questionnaire comprising 312 questions on social institutions and fully referenced country profiles, which followed a standardised structure to ensure comparability across countries/territories. Second, gender experts and/or government representatives with knowledge of the national policy and legal landscape for gender equality and women’s rights validated the responses. The cut-off date for the qualitative information was 30 June 2017. Publishing qualitative data (i.e. legal variables) across 180 countries is a multistage and complex process (data collection, process, management, validation and dissemination) that takes more than one year. This explains the delay between the collection cut-off date and the publication of the SIGI global data. All country profiles can be retrieved from the website www.genderindex.org.

A coding manual was created to quantify the level of legal discrimination based on the qualitative legal information collected. The coding manual ensures consistency across variables, guarantees objectivity in the selection criteria for scoring, and allows for comparability across countries as well as over time (see Annex B). Of the 312 questions, 144 were used to assign a discrete value to each of the 14 legal variables. The coding manual is based on all applicable legal frameworks, including civil, as well as customary, religious or traditional practices or laws. When information is missing or insufficient, variables do not receive a value. A five-level scale (0, 25, 50, 75 and 100) serves as the basis for encoding the categorical variables and reflects the level of discrimination in formal and informal laws (Table III).

Quantitative data

Quantitative information, such as attitudinal and prevalence data, was collected from various secondary data sources according to the country and variable. The OECD Development Centre’s Gender Team used international data sources – such as Demographic and Health Surveys (DHS), the World Values Survey (WVS) and the National Household Survey (NHS) – and then proceeded to harmonise the data in order to ensure comparability across countries. The cut-off date for the quantitative information was 31 December 2017.

SIGI scores and classification

The SIGI is a composite index. The scores for the overall index, the dimensions and the indicators range from 0 to 100, with 0 indicating no discrimination and 100 indicating absolute discrimination against women. In order to facilitate the analysis and presentation of results, countries are classified into five categories at the index level, as well as at the dimension and indicator levels. Table IV summarises the categories and the cut-off points of the different categories based on the SIGI and the dimension and indicator scores.

Table IV. Classification of countries based on SIGI scores and dimension/indicator scores
Level of discrimination	SIGI scores	Dimension/indicator scores
Very low	[0-20]	[0-10]
Low	[20-30]	[10-25]
Medium	[30-40]	[25-50]
High	[40-50]	[50-75]
Very high	[50-100]	[75-100]
Note: Both SIGI scores and dimension/indicator scores range from 0 to 100, with 0 indicating no discrimination and 100 indicating absolute discrimination.

Domestic violence	Violence that occurs within the private sphere, generally between individuals who are related through blood, intimacy or law	(CEDAW, 2017[6])
Equal access	Equal opportunities to have access to resources, assets, services, training and education opportunities, markets, sources of income and decent employment opportunities	(FAO, 2016[7])
Equal opportunity	Equality in employment regardless of race, skin colour, sex, religion and so forth; non-discriminatory practices in hiring employees	(United Nations, n.d.[8])
Female genital mutilation	All procedures involving partial or total removal of the external female genitalia or other injuries to the female genital organs for non-medical reasons	(United Nations, 2008[9])
