Every country in the world has some form of parliament. Parliamentary systems fall into two categories: bicameral and unicameral. Out of 193 countries in the world, 79 are bicameral and 114 are unicameral, making a total of 272 chambers of parliament with over 46,000 members of parliament. IPU membership is made up of 179 national parliaments. Discover the world's national

The IPU has been collecting data on parliaments since its inception in 1889, including information on women’s participation in politics since 1945. In this section, discover the IPU's knowledge bank for and about parliaments.
International Day of Parliamentarism 2018: Are parliamentary democracies in danger?
As the world celebrates for the first time, on 30 June, the International Day of Parliamentarism, data on parliaments shows a mixed picture.
This date was chosen by the United Nations General Assembly in Resolution 72/278 as it coincides with the day in 1889, close to 130 years ago, that the IPU—the global organization of parliaments—was founded.
What is the International Day of Parliamentarism? It is an opportunity to celebrate parliaments, as the cornerstone of democracy, and as institutions designed to improve the lives of the people they represent.
It’s also a time to take a snapshot of the state of parliaments in 2018, to monitor progression but also identify challenges. In an age of many problems – from climate change, mass movements of people, to the rise of populism and autocracy – the world needs its parliaments more than ever before.
From the IPU’s unique worldwide vantage point, and its privileged relationship with parliaments, we note some flashpoints. Are parliamentary democracies in danger? How can we protect the human rights of MPs in countries where they are under threat and actually violated? How can parliaments better represent women and young people? How can parliaments keep the trust of the people? How can parliaments develop to meet the challenges of today?
On this page, we attempt to answer some of those questions using IPU and other data, as well as 1-minute video interviews with some leading parliamentarians.
We also highlight some success stories as parliaments critically assess themselves, adapt to new technology, and take action to better represent people, and deliver on their expectations.
The IPU Committee on the Human Rights of Parliamentarians is currently examining the cases of over 550 MPs in 40 countries, one of the highest figures ever recorded. Most of the cases are from the Americas and Asia. A large majority of the cases, (75 percent) concern MPs from opposition parties. About 20 per cent of the cases concern women MPs. The most common violations include MPs being denied a fair trial, suspended from parliament or detained arbitrarily.
However, there is also some good news. Dato Seri Anwar Ibrahim, the former Deputy Prime Minister of Malaysia, was released from prison in May this year after being granted a full royal pardon. The IPU Committee on the Human Rights of Parliamentarians, which had been defending Mr. Anwar’s case since the 1990s, had consistently maintained that Mr. Anwar was the victim of an unfair trial and lobbied intensively over the years for his release.
Women’s participation in politics stagnates
The IPU has been pushing for gender parity in politics for decades by, for example, encouraging quotas of at least 30 or 50 percent of women parliamentarians depending on starting points.
Overall, there has been progress with women’s average share of parliamentary membership increasing from 17 per cent in 2007 to over 23 per cent today. The group of top 10 countries with the highest number of women MPs has also become more diverse in the last 10 years: the top 10, dominated by European countries in 1998, now also includes sub-Saharan Africa and the Americas.
However, this trend has stagnated recently. If current rates continue, it will take at least 250 years before we reach gender parity in parliaments.
For the second year in a row, the percentage of women in parliaments has barely budged, at 23.4 percent in 2017 compared to 23.3 in 2016. Before 2016, annual progress was 0.6 percent while in 2017 it dropped to 0.1 percent.
The percentage of women Heads of State stands at 7.2 in 2017: a slight increase on 6.6 percent in 2015.
However, the number of women heads of government has gone down from 7.3 percent in 2015 to 5.7 percent in 2017.
A 2016 IPU study found that 82 percent of women parliamentarians had experienced some kind of psychological violence.
Parliaments, often with IPU support, are rising to the challenge. Women’s parliamentary caucuses are proving to be useful mechanisms to consult women and channel their needs into the work of parliaments. The support provided by the IPU to women’s parliamentary caucuses is beginning to generate tangible results. For example, in 2017, IPU support allowed Mauritania’s caucus of women MPs to travel around the country to consult with women and girls, particularly in rural areas. Following the consultations, MPs of both genders were able to address the socio-economic needs of rural women and girls in the parliament.
Young people continue to be excluded from political decisions that affect their future
Young people also remain vastly under-represented in political decision-making.
Although 51 percent of the world’s population is under 30, young people under 30 account for less than 2 per cent of the world’s MPs.
Nearly one third of the world’s single or lower houses of parliament have no MPs aged under 30.
Young women are the least represented of all on account of being women and because they are young.
Youth political apathy is also a concern. Young people aged 25 and under are much less likely to turn out to vote than those who are 26 and above. Recent research by the International Institute for Democracy and Electoral Assistance on voter turnout shows that 33 percent of eligible voters under 25 have never voted.
However, some countries are taking concrete steps to engage more with youth. For example, in a historic step in May this year, Nigerian President Muhammadu Buhari signed into law the Not Too Young to Run bills that lower the ages of eligibility for people to run for office and hold government positions.
The sponsor of one of the bills was a young parliamentarian himself. Raphael Igbokwe is the President of the Nigerian Forum of Young MPs and a former member of the IPU’s Forum of Young Parliamentarians.
People’s trust in political institutions is declining...
The public’s trust in political institutions – including parliaments – has been undermined in recent decades by prominent scandals, allegations of corruption, and other breaches of acceptable behaviour by elected officials across the world.
The Economist Intelligence Unit Democracy Index 2016 found that between 2006 and 2016 democracy has stagnated or regressed. Almost half of the 176 countries covered by the Democracy Index registered an overall decline.
In the last 10 years, requests for the IPU’s technical assistance have doubled as more and more parliaments ask for help to face these challenges . Based on more than four decades of experience on parliamentary development, the Common Principles for Support to Parliament, designed by the IPU together with partners, offer guidelines for those receiving or providing support to parliaments. The guidelines are designed to improve the quality of the support and to encourage the parliamentary community to work together more effectively.
A total of 122 parliaments and partner organizations have endorsed the Common Principles to date.

 In October, the IPU will publish a new, more extensive, study entitled “Regional research on sexism, harassment and violence against women in parliaments in Europe” in partnership with the Parliamentary Assembly of the Council of Europe.
