By 2020, African countries will fully exploit mobile devices and the internet to conduct demographic and housing censuses more speedily and cost effectively, hence enhancing decision making for the achievement of the Sustainable Development Goals (SDGs).
This is what underpins a training workshop for high-level statisticians from all over Africa, taking place in Yaounde, Cameroon, at the behest of the UN Economic Commission for Africa (ECA) in partnership with the United Nations Statistics Division (UNSD) and the Government of Cameroon.
The Yaounde encounter which has brought together over 40 experts is the last in a series of regional consultations coordinated by the United Nations Statistics Division in order to get feedback on draft guidelines on the use of electronic data collection technologies in population and housing censuses that will serve as reference at the global level once finalized.
The workshop, which has been described as ‘timely’ by various stakeholders, comes at a time when the world counts about 5 billion mobile telephone network subscribers, from all walks of life, who could be linked through the right platforms and technologies to facilitate data collection and the conduct of modern censuses.
his will “provide speed, accuracy, ubiquity, familiarity and convenience” which “can yield good value for money results in such complex operations as population censuses” as the Director of the Sub-Regional Office for Central Africa of ECA, Mr. Antonio Pedro underscored.
Mr. Pedro however cautioned that the use of such technologies in censuses may come with challenges including “those related to technology changes, speed of change and resistance to change, high training costs and data security.” This, he said, calls for “collaboration between institutions in the use of mobile technology in order to better tackle new challenges and harness the full potential offered by mobile technology to the community of official statistics.”
Such collaboration is already being well played out between Cameroonian and Malian statisticians as pointed out by Dr Teke Johnson Takwa who heads the Unit for Data Analysis of Cameroon’s Central Bureau for Census and Population Studies (BUCREP).
He said following the first phase of the 10th Development Account project on the use of mobile and internet devises for censuses, conducted by ECA, BUCREP has been for there years effectively using the devices alongside other techniques Cameroon acquired from that phase with positive results and has shared its advanced experiences with Malian counterparts.
Dr Takwa and his colleague of Cameroon’s National Institute of Statists (NIS) – Mr. Anaclet Désiré Dzossa, were thankful to ECA’s African Centre for Statistics (ACS) for operationalizing the said Development Account in Africa since 2015, which has given them the tools and techniques that Cameroon has so far used in three major areas: carrying out surveys of market item prices, collecting data around tobacco consumption and conducting Cameroon’s 5th demographic survey (which is ongoing).
As the consultations for finalizing the UNSD guidelines come to an end with this last series of workshops to enhance census processes by 2020, the UNSD is making sure statisticians in Africa, like their colleagues elsewhere, are are on the same page on the use of electronic data collection technologies in population and housing censuses.
This explains the presence of Ms. Meryem Demirci, UNSD’s Interregional Advisor on Population and Housing Censuses, at the Yaounde meeting. UNSD also hopes to use the Yaounde workshop to collect input from the African statisticians in attendance, to perfect the guidelines in question, for use across the globe.















![Canon makes history with 170 Million lenses milestone Canon’s RF/EF lens production exceeds 170 million units, extending its world record in interchangeable lens production Both EF and RF lenses have gained strong support from a wide range of users—from beginners to professionals—leading to steady growth in production volume Canon Inc. announced that, in October 2025, Canon reached a historic milestone of producing a cumulative total of 170 million RF and EF interchangeable lenses for its EOS series, extending its world record for the highest number of interchangeable camera lenses ever produced. The EF lens was introduced in 1987 as the dedicated lens system for Canon’s EOS autofocus single-lens reflex film camera, debuting simultaneously with the EOS system itself. Since their inception, EF lenses have led the industry by incorporating a series of world-first technologies, including the Ultrasonic Motor (USM), Image Stabilizer (IS) technology, and a multilayered Diffractive Optical (DO) element, and have undergone numerous evolutions. In 2018, Canon launched the RF lens series, designed for the EOS R mirrorless camera system, which features a large aperture, short back focus, and high-speed communication system to deliver even higher image quality. The RF and EF lens series lineup now includes a total of 108 models , covering a wide range of focal lengths from ultra-wide 10mm to super-telephoto 1200mm. The series also includes the world’s first VR lens lenses with built-in power zoom suited for video shooting, and even those compatible with power zoom adapters—expanding the scope of creative expression and meeting the diverse needs of users for both still photography and video. EF lens production began at Canon’s Utsunomiya Plant in 1987. Since then, both EF and RF lenses have gained strong support from a wide range of users—from beginners to professionals—leading to steady growth in production volume. Today, Canon manufactures lenses at five sites: Utsunomiya Plant; Canon Inc., Taiwan; Canon Opto (Malaysia) Sdn. Bhd.; Oita Canon Inc.; and Miyazaki Canon Inc. Milestones include 10 million units produced by 1995 and 50 million by 2009. Then in 2014, Canon became the first company in the world to reach 100 million interchangeable camera lenses produced. In October 2025, the company reached 170 million units, leading to the achievement of this world record. The 170 millionth lens produced was the RF 70-200mm F2.8 L IS USM Z. Canon has maintained the No.1 global market share for digital interchangeable-lens cameras for 22 consecutive years since 2003. Moving forward, Canon will continue to refine its proprietary imaging technologies and further strengthen and expand its lens lineup, pioneering new imaging possibilities and contributing to the continued evolution of photographic and video culture. Highlights in the development of the RF/EF Lens Series The EF lens, which was introduced alongside EOS in March 1987, has adopted a variety of world-first technologies, including Image Stabilizer (IS) technology, featured in the EF 75-300mm f/4-5.6 IS USM released in 1995; a multilayered Diffractive Optical (DO) element, used in the EF 400mm f/4 DO IS USM launched in 2001; and Subwavelength Structure Coating (SWC) [7], applied to the EF 24mm f/1.4L II USM released in 2008. In 2021, Canon launched the EOS VR System, a VR video system consisting of a mirrorless camera [8], dedicated lens, and PC software, thereby creating a 3D 180° VR video through an interchangeable lens camera. In 2024, Canon began rolling out a new series of hybrid lenses equipped with iris rings, designed to meet the needs of both still photography and professional video production. For zoom lenses, the company has also launched RF 24-105mm F2.8 L IS USM Z and RF 70-200mm F2.8 L IS USM Z which are compatible with power zoom adapters. For single focus lenses, the company released F1.4 L hybrid prime lens series that unified the size and ring and button position across models. In September 2025, Canon launched RF 85mm F1.4 L VCM, the fifth model in this series, demonstrating that it can meet demands in line with the changing times.
