In this article, we’ll list countries expected to be the most populated in 2030 and their population growth patterns. If you want to skip how the world’s population trends are changing, read 10 Most Populated Countries in 2030.

Patterns in the World’s Population Growth

As we approach 2030, it is crucial to understand the dynamics of population growth. Estimates suggest that the world’s population will reach 8.5 billion by 2030 and exceed 10 billion by 2050, a significant increase from 6 billion in 2000. But intriguingly, in 2000, the world’s average fertility rate was 2.7 births per woman, exceeding the 2.1 births required to replace the existing population. By 2023, this rate has decreased to 2.3 births per woman and continues to decline, particularly in economically advanced countries.

An analysis of fertility rate patterns by region reveals that the rate is 1.6 births per woman in OECD countries, 2.3 in Asia, and 4.2 in Africa. This pattern suggests a greater population burden in economically disadvantaged countries, many of which are projected to be among the most populated in the world by 2050.

Since the developments in the healthcare sector have increased the population’s average life expectancy from 64 years in 1990 to 73 years in 2023, it’s important to note that a significant portion of the population will be elderly moving forward. According to the United Nations Department of Economic and Social Affairs (UN DESA), there were 761 million people aged 65 and older in 2021. The number is projected to reach 1.6 billion by 2050. In the next two decades, approximately one in six people will be 65 years or older, compared to the current ratio of 1 in 10.

The aging population will lead to increased demand for healthcare services and age-related support, straining public health systems and elevating healthcare spending. The labor market will face a shrinking workforce, potentially leading to labor shortages and increased pressure on younger generations to sustain economic productivity.

Family Planning and its Impact on Population Growth

The United Nations Population Fund estimates that nearly half of the global pregnancies are unintended, totaling approximately 121 million per year. The report also states that about 60% of these unintended pregnancies result in abortions. However, as 45% of abortions are considered risky, they contribute to 5-13% of maternal deaths annually.

Therefore, to manage the population burden in the most populated countries and protect women’s health, there is a need for safer and more affordable contraceptive methods to be more accessible. Impressively, from 2000 to 2020, the number of women using contraceptives increased from 663 million to 851 million. Due to the prevalence of modern contraceptives, Precedence Research reports that the global contraceptive industry was valued at $16 billion in 2022 and is projected to reach $27.72 billion by 2032, growing at a compound annual growth rate (CAGR) of 5.70%.

The World Health Organization (WHO) reported that in 2022, approximately 77.5% of women of reproductive age (15–49 years) globally had their family planning needs met using modern contraceptive methods. This figure represents a growth of 10 percentage points from 67% in 1990. Notably, the gradual increase can be attributed to the limited options for contraceptives and concerns regarding their side effects.

A PubMed study found that about 51% of women continued using oral contraceptives (OCPs) once they started, compared to 77% who preferred copper IUDs (intrauterine devices). Similarly, 84% of women in the study group continued with LNG-IUS (levonorgestrel intrauterine systems), while 85% maintained the use of contraceptive implants. These results indicate a trend that young women more consistently used longer-lasting methods like IUDs and implants as they were more effective in preventing pregnancy compared to birth control pills. In simpler terms, methods that do not require daily attention were more successful in regular usage and in preventing unwanted pregnancies.

Regarding the efficacy of these contraceptive methods in helping countries with the highest rates of population growth, the PubMed study reports that OCPs had a pooled estimated pregnancy rate. i.e., chances of getting pregnant when on a contraceptive of 11%. On the other hand, copper IUDs had a rate of 5%, LNG-IUS 1.6%, and implants 1.8%. These findings further reinforce that the most effective birth control methods are the long-term ones, although their side effects are a separate matter of discussion.

Modern Contraceptives and Their Impact

With growing populations exerting strain on resources, the need for effective and accessible contraceptive methods is more pressing than ever. This necessity is fundamentally linked to the empowerment and health of women, as easy access to contraception enables them to manage their reproductive health and reduce risks associated with unintended pregnancies.

Tel-Aviv-based Teva Pharmaceutical Industries Ltd (NYSE:TEVA) contributes to this need by producing a variety of pharmaceuticals, including women’s healthcare products, oral contraceptives, and intrauterine devices. Teva Pharmaceutical Industries Ltd (NYSE:TEVA) owns Barr Pharmaceuticals, Inc., which in turn owns Duramed Pharmaceuticals, Inc., the maker of ParaGard T-380A. This 100% hormone-free copper-T IUD, around 99% effective, is the oldest FDA-approved copper IUD in the US. Notably, Teva Pharmaceutical Industries Ltd (NYSE:TEVA)’s ParaGard is the only copper contraceptive device available in the US and is well-regarded as it can prevent pregnancy for 10 years after insertion.

Similarly, Pfizer Inc. (NYSE:PFE) manufactures Depo-Provera Contraceptive Injection, administered every three months. The Depo injection by Pfizer Inc. (NYSE:PFE) contains the progestin hormone, which suppresses ovulation and is approximately 96% effective. Pfizer Inc. (NYSE:PFE)’s Depo offers a convenient birth control method, requiring only four injections a year, and is suitable for women who cannot use estrogen-based contraceptives.

Merck & Co., Inc. (NYSE:MRK) also leads in modern contraceptive solutions, manufacturing NuvaRing, a combined hormonal contraceptive vaginal ring. Moreover, Merck & Co., Inc. (NYSE:MRK) makes Implanon, a long-acting reversible hormonal birth control implant. Merck & Co., Inc. (NYSE:MRK) ‘s NuvaRing releases a continuous low dose of estrogen and progestin, functioning for three weeks at a time. Its localized hormone application often leads to fewer systemic side effects compared to oral contraceptives.

While contraception is one aspect of managing population growth, these birth control methods have already made an impact in advanced countries. They enable better family planning, improve women’s health, and contribute to more stable population growth. Extending similar access to contraceptives in less developed regions, particularly the most populated countries in 2030, could effectively manage population growth. Intended and responsible conception promotes sustainable development, lowers healthcare costs, and contributes to a more balanced demographic structure.

On that note, let’s now discuss the top populated countries by 2030!

50 Most Populated Countries In 2030

Our Methodology

We consulted the World Bank’s data on population projections to identify the countries expected to be the most populated in 2030. These countries are ranked in ascending order based on the estimates. The projections consider trends in population growth, fertility rates, life expectancy, and migration patterns. It’s important to note that these estimates may change due to factors such as government policies, economic conditions, and unforeseen events that could influence population dynamics.

Here are the countries that will have the biggest populations in 2030:

50. Poland

Projected Population in 2030: 34.4 million

Poland’s population is declining due to an aging populace and decreasing birth rates, a trend common across Europe. Although the population is projected to shrink to 30 million by 2050, it is estimated to be 34.4 million by the decade-end, putting Poland among the most populated countries in 2030.

49. Niger

Projected Population in 2030: 35.2 million

Niger, characterized by one of the highest population growth rates globally at 3.66%, is experiencing a demographic shift. The country’s youthful and rapidly expanding population places it among the countries expected to be the most populated in 2030.

48. Madagascar

As of 2023, Madagascar’s population has reached approximately 30.3 million, marking a 2.41% increase from 2022. This growth trend has been consistent over recent years, with similar increases observed annually. The country’s diverse population, predominantly youthful with a significant portion under 15, remains largely rural. However, there is a noticeable trend towards urbanization. Cities like Antananarivo expand as people seek better economic opportunities and transition from traditional living patterns.

47. Malaysia

Projected Population in 2030: 36.6 million

Malaysia’s diverse demographic, including Malay, Chinese, Indian, and indigenous populations, is experiencing growth driven by natural increase and immigration, particularly in urban areas like Kuala Lumpur. Malaysia’s population growth, linked to its economic development, attracts international migration, positioning it among the most populated countries in 2030.

46. Peru

Projected Population in 2030: 36.7 million

Peru’s population, comprising significant indigenous, European, African, and Asian descent groups, experiences a growth rate of 0.8% per year on average. Factors contributing to this increase can include improved healthcare, leading to lower mortality rates and sustained birth rates.

45. Ghana

Projected Population in 2030: 38.7 million

Ghana, one of the countries with the highest poverty rates, has approximately 25% of its population living on less than $2.15 a day. Despite significant poverty and inadequate healthcare, the country’s population is anticipated to increase to 38.7 million in 2030, up from 25.5 million in 2010.

44. Uzbekistan

Projected Population in 2030: 39.4 million

UNICEF reports that about 60% of Uzbekistan’s population is under 30 years of age, reflecting high birth rates. This places Uzbekistan among the countries with the biggest populations in 2030. Furthermore, in the next two decades, this young population is poised to constitute Uzbekistan’s largest workforce, offering promising socioeconomic development opportunities.

43. Morocco

Projected Population in 2030: 40.2 million

Predominantly Arab-Berber, Morocco’s population is growing, particularly in cities like Casablanca and Marrakech.

42. Saudi Arabia

Projected Population in 2030: 40.4 million

A significant portion of Saudi Arabia’s population is under 30 and predominantly urban, concentrated in cities such as Riyadh and Jeddah. The country’s economic status, bolstered by its oil wealth, influences its population dynamics, including migration patterns. Currently, 38.6% of its population is foreign-born, placing it among countries with the highest proportion of immigrants.

41. Ukraine

Projected Population in 2030: 40.6 million

Due to emigration and a low birth rate, Ukraine’s population is declining and is anticipated to reach 35 million by 2050. Nevertheless, its projected population of 40.6 million by 2030 remains one of the highest in the world.

40. Mozambique

Projected Population in 2030: 40.9 million

Mozambique’s population growth is driven by high fertility rates, significantly influencing its social and economic policies. The country also faces severe poverty, exacerbated by reduced foreign investment and natural disasters.

39. Canada
