The world population surpassed eight billion people in 2022, having doubled from its figure less than 50 years previously. Looking forward, it is projected that the world population will reach nine billion in 2038, and 10 billion in 2060, but it will peak around 10.3 billion in the 2080s before it then goes into decline. Regional variations The global population has seen rapid growth since the early 1800s, due to advances in areas such as food production, healthcare, water safety, education, and infrastructure, however, these changes did not occur at a uniform time or pace across the world. Broadly speaking, the first regions to undergo their demographic transitions were Europe, North America, and Oceania, followed by Latin America and Asia (although Asia's development saw the greatest variation due to its size), while Africa was the last continent to undergo this transformation. Because of these differences, many so-called "advanced" countries are now experiencing population decline, particularly in Europe and East Asia, while the fastest population growth rates are found in Sub-Saharan Africa. In fact, the roughly two billion difference in population between now and the 2080s' peak will be found in Sub-Saharan Africa, which will rise from 1.2 billion to 3.2 billion in this time (although populations in other continents will also fluctuate). Changing projections The United Nations releases their World Population Prospects report every 1-2 years, and this is widely considered the foremost demographic dataset in the world. However, recent years have seen a notable decline in projections when the global population will peak, and at what number. Previous reports in the 2010s had suggested a peak of over 11 billion people, and that population growth would continue into the 2100s, however a sooner and shorter peak is now projected. Reasons for this include a more rapid population decline in East Asia and Europe, particularly China, as well as a prolonged development arc in Sub-Saharan Africa.

Kenya is committed to achieving Universal Health Coverage (UHC) within its devolved health system in which significant investments have been made in health infrastructure, workforce development, and service delivery. Despite these efforts, the country faces considerable health workforce challenges. To address these, the Ministry of Health undertook a comprehensive Health Labour Market Analysis (HLMA) in 2022 to generate evidence supporting the development of responsive health workforce policies. This paper presents findings of a modelling exercise to understand the health labour market outlook. As part of a comprehensive HLMA, a validated needs-based health workforce modelling framework was applied to project the supply, needs, and investment requirements. Data was triangulated from multiple sources through desk reviews and group modelling by an expert technical working group constituted to undertake the study. The analysis considered disease burden, population growth, service delivery models, and health worker productivity, to assess the future health workforce needed. Kenya’s health workforce is growing, with approximately 7,650 new workers added annually, resulting in an estimated 3.4% annual growth. By 2025, the health workforce is projected to reach 226,434, increasing to 263,700 by 2030. However, Kenya required a minimum of 254,220 health workers in 2021 to make substantial progress toward UHC. The cumulative need could rise to 476,278 by 2035. In 2021, Kenya had a needs-based shortage of nearly 60,000 health professionals, which could increase to 114,352 by 2030. The financial space for health workforce was estimated at US$2.29 billion in 2021 and is projected to rise to US$3.58 billion by 2030, but the required wage bill potentially reaching US$3.9 billion. Kenya must significantly increase investments in its health workforce to meet UHC goals. Both public and private sectors need to contribute more, with the public sector requiring a health workforce budget increase of 10.5% annually to bridge the projected funding gap.

              Social media: trust and consumption

              Despite the majority of adults surveyed in each country reporting that they used social networks to keep up to date with news and current affairs, a 2018 study showed that social media is the least trusted news source in the world. Less than 35 percent of adults in Europe considered social networks to be trustworthy in this respect, yet more than 50 percent of adults in Portugal, Poland, Romania, Hungary, Bulgaria, Slovakia and Croatia said that they got their news on social media.

              What is clear is that we live in an era where social media is such an enormous part of daily life that consumers will still use it in spite of their doubts or reservations. Concerns about fake news and propaganda on social media have not stopped billions of users accessing their favorite networks on a daily basis.
              Most Millennials in the United States use social media for news every day, and younger consumers in European countries are much more likely to use social networks for national political news than their older peers.
