This statistic shows the total population of Sub-Saharan Africa from 2013 to 2023. Sub-Saharan Africa includes all countries south of the Sahara desert. In 2023, the total population of Sub-Saharan Africa amounted to approximately 1.26 billion inhabitants.

In 2022, around 55 percent of the total population of Sub-Saharan Africa was aged 15 to 64 years. Moreover, children younger than 15 years constituted a large 42 percent of the inhabitants. Overall, Africa has a young population. Only three percent of the individuals in the Sub-Saharan region were aged 65 years and older. As of 2023, Niger, Uganda, Angola, and Mali had a median age below 16.5 years, the lowest on the continent.

Nearly eight million refugees lived in Sub-Saharan Africa in 2023. The refugee population in the region has enormously increased in the last decade. As of 2010, 2.2 million individuals forcibly displaced dwelled in Sub-Saharan Africa. Uganda hosted the largest number of refugees in Africa.

This statistic shows the population change in Sub-Saharan Africa from 2013 to 2023. Sub-Saharan Africa includes almost all countries south of the Saharan desert. In 2023, Sub-Saharan Africa's population increased by approximately 2.5 percent compared to the previous year.

Social distancing is a public health measure intended to reduce infectious disease transmission, by maintaining physical distance between individuals or households. In the context of the COVID-19 pandemic, populations in many countries around the world have been advised to maintain social distance (also referred to as physical distance), with distances of 6 feet or 2 metres commonly advised. Feasibility of social distancing is dependent on the availability of space and the number of people, which varies geographically. In locations where social distancing is difficult, a focus on alternative measures to reduce disease transmission may be needed. To help identify locations where social distancing is difficult, we have developed an ease of social distancing index. By index, we mean a composite measure, intended to highlight variations in ease of social distancing in urban settings, calculated based on the space available around buildings and estimated population density. Index values were calculated for small spatial units (vector polygons), typically bounded by roads, rivers or other features. This dataset provides index values for small spatial units within urban areas across Sub-Saharan Africa. Measures of population density were calculated from high-resolution gridded population datasets from WorldPop, and the space available around buildings was calculated using building footprint polygons derived from satellite imagery (Ecopia.AI and Maxar Technologies. 2020). These data were produced by the WorldPop Research Group at the University of Southampton. This work was part of the GRID3 project with funding from the Bill and Melinda Gates Foundation and the United Kingdom’s Department for International Development. Project partners included the United Nations Population Fund (UNFPA), Center for International Earth Science Information Network (CIESIN) in the Earth Institute at Columbia University, and the Flowminder Foundation.

In 2022, the share of the population with access to electricity in Sub-Saharan Africa increased by 0.9 percentage points (+1.78 percent) compared to 2021. With 51.43 percent, the share thereby reached its highest value in the observed period. Access to electricity refers to the share of the population having the possibility to access electricity

Less than half the population in all the Sub-Saharan African countries included had access to safely managed drinking water in 2022. The share was lowest in the Central African Republic and Chad, where only six percent of the population had access to clean drinking water. Worldwide, Sub-Saharan Africa was the region with the lowest share of access to clean drinking water.

Drosophila melanogaster has played a pivotal role in the development of modern population genetics. However, many basic questions regarding the demographic and adaptive history of this species remain unresolved. We report the genome sequencing of 139 wild-derived strains of D. melanogaster, representing 22 population samples from the sub-Saharan ancestral range of this species, along with one European population. Most genomes were sequenced above 25X depth from haploid embryos. Results indicated a pervasive influence of non-African admixture in many African populations, motivating the development and application of a novel admixture detection method. Admixture proportions varied among populations, with greater admixture in urban locations. Admixture levels also varied across the genome, with localized peaks and valleys suggestive of a non-neutral introgression process. Genomes from the same location differed starkly in ancestry, suggesting that isolation mechanisms may exist within African populations. After removing putatively admixed genomic segments, the greatest genetic diversity was observed in southern Africa (e.g. Zambia), while diversity in other populations was largely consistent with a geographic expansion from this potentially ancestral region. The European population showed different levels of diversity reduction on each chromosome arm, and some African populations displayed chromosome arm-specific diversity reductions. Inversions in the European sample were associated with strong elevations in diversity across chromosome arms. Genomic scans were conducted to identify loci that may represent targets of positive selection within an African population, between African populations, and between European and African populations. A disproportionate number of candidate selective sweep regions were located near genes with varied roles in gene regulation. Outliers for Europe-Africa FST were found to be enriched in genomic regions of locally elevated cosmopolitan admixture, possibly reflecting a role for some of these loci in driving the introgression of non-African alleles into African populations.

BackgroundEpilepsy is a major public health issue worldwide, often leading to physical and cognitive impairments that limit employment, independence, and social interaction. Health-related quality of life (HRQoL) is a crucial outcome in the treatment of chronic epilepsy as it is linked to reduced independence, treatment challenges, and lower life expectancy. HRQoL serves as an important health indicator for assessing the impact of the disease on daily living activities.ObjectiveThis study aimed to estimate the mean score of health-related quality of life (HRQoL) and factors associated with lower HRQoL in people living with epilepsy (PLWE) in sub-Saharan African (SSA) countries.MethodsA comprehensive literature search was conducted using PubMed, Cochrane Library, Scopus, and Google Scholar databases. This review has been registered with PROSPERO (CRD42024620363). The eligibility criteria were established, and this review included cross-sectional and observational studies assessing HRQOL in PLWE in SSA countries, published in English from the inception of databases through November 2024. The pooled HRQoL was reported as the mean score with accompanying 95% confidence intervals. Finally, publication bias was evaluated using a funnel plot and Egger’s regression test.ResultsThe pooled mean score of HRQoL among PLWE in SSA was 63.79 (95% CI: 59.75–67.84%). Owing to significant heterogeneity across the studies, a random-effects model was utilized for the meta-analysis (I2 = 98.96%, p

BackgroundA persistent treatment gap remains between children and adults living with HIV. The Zvandiri program, developed by Africaid, is one of the few models of differentiated service delivery for children, adolescents, and youth that has been shown to improve outcomes along the HIV care continuum, employing Community Adolescent Treatment Supporters (CATS) to offer peer counseling and patient navigation. Our qualitative study provides an in-depth analysis of the feelings and experiences Zimbabwean youth had following an HIV diagnosis, and the ways that CATS facilitated linkage and retention in care.MethodsWe conducted in-depth interviews in Shona with adolescents and young adults who were recently diagnosed with HIV in Zimbabwe. Interviews were audio-recorded, transcribed, and then translated to English. Interviews were coded in Dedoose using a structured a priori codebook. We wrote semi-structured summary memos for each interview. We co-conducted thematic analysis, guided by interpretive phenomenology with a team of Zimbabwean and American experienced qualitative researchers and community partners. We co-developed memos to elaborate and understand key themes across interviews.ResultsMost of our interview participants recounted an immediate sense of loss upon testing HIV positive and a fear that “there was no hope for the future.” CATS played a pivotal role for youth, providing emotional, educational, and logistical support to facilitate treatment initiation, adherence, and persistence in care. The CATS program supported youth through multiple approaches: group sessions, individual meetings, and via text or phone. While CATS offered counseling and comfort to participants, they emphasized the long-term importance of identifying at least one other person in participants’ lives who could know their status and support them around HIV.ConclusionOur findings delineate some of the key concerns that face youth after receiving an HIV diagnosis and the ways that a community-based adherence peer navigation program supported participants to navigate both their feelings and the health care system. Results can inform practice at community-based agencies that are implementing or considering peer youth navigation programs and garner support for policy to fund interventions for youth.

Christianity is the main religion in Sub-Saharan Africa. As of 2020, 62 percent of the region's population was Christian. Muslims followed, accounting for 31.4 percent of the total population. In addition, 3.2 percent of the people in Sub-Saharan Africa practiced traditional African religions, while the unaffiliated constituted three percent of the population.

In 2022, an estimated 91 percent of the world population had access to at least basic drinking water services. Access was highest in Europe and North America and Australia and New Zealand, with approximately 100 percent of both regions having access to at least basic drinking water services.

Access to safe drinking water

Improved drinking water refers to a source that can be adequately protected from outside contamination, mostly by fecal matter. An improved sanitation facility keeps human waste out of reach, for example, by using a flush toilet or a septic tank. These protected sources include rainwater, protected springs, and piped water into a dwelling. Global investments in water supply infrastructure are expected to increase.

Global water inequality

In most regions of the world, 90 percent of the population has access to at least basic drinking water services. However, just 65 percent of the population in sub-Saharan Africa and 60 percent of the population in Oceania had basic access in 2022. In sub-Saharan Africa, about 16 percent of people had access to unimproved water sources and eight percent only had access to surface waters. Unimproved water sources include bottled water and tanker-trucks. Currently, eight out of ten people living in rural areas still lack even basic drinking water services. A lack of access to safe water is considered one of the top risks based on impact to global societies.
