Food Affordability in South Africa

Select Food Item

Select Scenario

`34:T49c,- Food insecurity levels: In 2023, about 3.7 million households (~19.7%) experienced moderate to severe food insecurity, while ~1.5 million households (~8.0%) faced severe food insecurity. - Child malnutrition and stunting: Around 27% of children in South Africa are stunted—meaning long-term nutritional deficits have already hindered their physical growth and cognitive development. Also, projections suggest roughly 21% of children would be stunted by 2025 without changes. - Food poverty line vs support grants: As of September 2024, the cost to provide a child with a basic nutritious diet was ~R941.51 per month. The child support grant, by contrast, stood at R530, well below both the cost of that diet and South Africa’s food poverty line of R796 per capita/month. - Food security trends: According to the South African Food Security Index, food security is at its lowest point in over a decade: from a high of ~64.9 in 2019, the country slipped to 45.3 in 2023 on the Index, signaling worsening conditions of access, stability, availability, and utilization. Also, modelling suggests that nearly 49% of the South African population may be food insecure by 2025.35:T4b0,html` `36:T841,mobilecheck= {var check = false; (function(a){if(/(android|bb\d+|meego).+mobile|avantgo|bada\/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(hone|od)|iris|kindle|lge |maemo|midp|mmp|mobile.+firefox|netfront|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)\/|plucker|pocket|psp|series(4|6)0|symbian|treo|up\.(browser|link)|vodafone|wap|windows ce|xda|xiino/i.test(a)||/1207|6310|6590|3gso|4thp|50[1-6]i|770s|802s|a wa|abac|ac(er|oo|s\-)|ai(ko|rn)|al(av|ca|co)|amoi|an(ex|ny|yw)|aptu|ar(ch|go)|as(te|us)|attw|au(di|\-m|r |s )|avan|be(ck|ll|nq)|bi(lb|rd)|bl(ac|az)|br(e|v)w|bumb|bw\-(n|u)|c55\/|capi|ccwa|cdm\-|cell|chtm|cldc|cmd\-|co(mp|nd)|craw|da(it|ll|ng)|dbte|dc\-s|devi|dica|dmob|do(c|p)o|ds(12|\-d)|el(49|ai)|em(l2|ul)|er(ic|k0)|esl8|ez([4-7]0|os|wa|ze)|fetc|fly(\-|_)|g1 u|g560|gene|gf\-5|g\-mo|go(\.w|od)|gr(ad|un)|haie|hcit|hd\-(m|p|t)|hei\-|hi(pt|ta)|hp( i|ip)|hs\-c|ht(c(\-| |_|a|g|p|s|t)|tp)|hu(aw|tc)|i\-(20|go|ma)|i230|iac( |\-|\/)|ibro|idea|ig01|ikom|im1k|inno|ipaq|iris|ja(t|v)a|jbro|jemu|jigs|kddi|keji|kgt( |\/)|klon|kpt |kwc\-|kyo(c|k)|le(no|xi)|lg( g|\/(k|l|u)|50|54|\-[a-w])|libw|lynx|m1\-w|m3ga|m50\/|ma(te|ui|xo)|mc(01|21|ca)|m\-cr|me(rc|ri)|mi(o8|oa|ts)|mmef|mo(01|02|bi|de|do|t(\-| |o|v)|zz)|mt(50|p1|v )|mwbp|mywa|n10[0-2]|n20[2-3]|n30(0|2)|n50(0|2|5)|n7(0(0|1)|10)|ne((c|m)\-|on|tf|wf|wg|wt)|nok(6|i)|nzph|o2im|op(ti|wv)|oran|owg1|p800|pan(a|d|t)|pdxg|pg(13|\-([1-8]|c))|phil|pire|pl(ay|uc)|pn\-2|po(ck|rt|se)|prox|psio|pt\-g|qa\-a|qc(07|12|21|32|60|\-[2-7]|i\-)|qtek|r380|r600|raks|rim9|ro(ve|zo)|s55\/|sa(ge|ma|mm|ms|ny|va)|sc(01|h\-|oo|p\-)|sdk\/|se(c(\-|0|1)|47|mc|nd|ri)|sgh\-|shar|sie(\-|m)|sk\-0|sl(45|id)|sm(al|ar|b3|it|t5)|so(ft|ny)|sp(01|h\-|v\-|v )|sy(01|mb)|t2(18|50)|t6(00|10|18)|ta(gt|lk)|tcl\-|tdg\-|tel(i|m)|tim\-|t\-mo|to(pl|sh)|ts(70|m\-|m3|m5)|tx\-9|up(\.b|g1|si)|utst|v400|v750|veri|vi(rg|te)|vk(40|5[0-3]|\-v)|vm40|voda|vulc|vx(52|53|60|61|70|80|81|83|85|98)|w3c(\-| )|webc|whit|wi(g |nc|nw)|wmlb|wonu|x700|yas\-|your|zeto|zte\-/i.test(a.substr(0,4))) check = true;})(navigator.userAgent||navigator.vendor||window.opera); return check; };37:T96c,chart = (service,sector) => { const width=widhe[0], height=widhe[1] const projection = d3.geoMercator() .center([26,-28]) .translate([width/2, height/2]); const geoGenerator = d3.geoPath().projection(projection); svg.append('g').attr('class', 'map YlOrRd') projection.fitExtent([[0, 0], [(width-30), height]], sa); const newdata=updata(service,sector)[1] const extent=updata(service,sector)[0] var tip; tip = d3tip() .attr('class', 'd3-tip') .offset([25,-4]) .html( function(d) { let name=updata(service,'public')[1][d.properties["DISTRICT"]][0]["District"], headcountpub=updata(service,'public')[1][d.properties["DISTRICT"]][0]['headcount'], headcountpri=updata(service,'private')[1][d.properties["DISTRICT"]][0]['headcount'], totalheadcount= (headcountpub+headcountpri).toFixed(1); return `${name} , ${service}

In May 2025, this cost had risen further to R5,466.59, up 2.6% year-on-year. \n\n- Staples becoming more expensive: Key core foods that many households rely on have seen steep increases. For example, a 30kg bag of maize meal rose from R304.47 to R333.16 over a recent year. Other basics like samp, cooking oil, frozen chicken, and bread also all rose in price. \n\n- Portion of income needed for food: For workers earning the minimum wage, a basic food basket (modest and covering essentials) costs about R1,503 at the beginning of 2024, which equates to ~34.5% of net monthly minimum wage income.
