Global parliament index

understanding electoral landscapes

2024 was a momentous year for the ballot: over 2 billion people voted for political leaders in forty countries, in an unprecedented number of elections in a single year.  

To reflect this record-breaking year of voting, the Global Parliament Index seeks to analyse what this new political map of the world means for us all. And it should worry everyone who supports democracy.  

In a first of its kind study, the index analyses the political leanings of each government and places countries into one of ten categories based upon multiple factors; including the governing party’s policies, manifestos, and record in power. 

The global parliament

Our Global Parliament Index shows that most people living in Europe and North America are dominated by centre-right governments. And while each geographical region contains a mix of political hues; left-wing governments are more common in Latin America; and right-wing governments more common in Europe.  If each government represented a seat in a global parliament:  

  • The largest political grouping would be the centre-right with 307 seats, with dictatorships not far behind with 303.    
  • Even if every centre-right, centre-left and centrist government in the world entered an unlikely and very broad coalition, they would not secure a majority, representing just under 50% of the world’s population on 457 seats.     

Global Parliament Index 2025

This world map shows the government type in each of the world’s countries and the political alignment of its democracies on a scale from Populist Left through to Populist Right.

The Balance of Power

The study reflects the balance of political power across all governments aggregated into a single 1,000-member Global Parliament Index, with each MP representing about five million people. Where countries have smaller populations than the minimum number required per seat, they have been combined with other smaller countries that have the same government category.

Elections in 2025

At Arden we appreciate the vastly diverse political ideologies that exist across different countries. Defining how to classify political positions on a spectrum is an impractical task, particularly in an increasingly fragmented and polarised atmosphere. But with each significant national election there’s a golden opportunity to capture insight into the political state of the world at large.   

In 2024, over 2 billion people across 40 countries, representing approximately 50% of the global GDP, had the chance to elect a new leader. Electoral results saw significant political shifts and a trend of anti-incumbency. Voter frustration with economic and political issues led to major changes in leadership in several countries, highlighting a global desire for new directions and governance.  

The elections highlighted a common theme: declining support for incumbent leaders. Economic struggles like inflation and the rising cost of living played a major role in voter dissatisfaction, leading to significant political shifts worldwide. Many ruling parties either lost power or saw their majorities dramatically reduced. 

The resulting ideological landscape is mixed. Countries like the United States, Portugal, and Panama have experienced a shift to the right. In contrast, South Korea and the United Kingdom have leaned towards the left. A particularly striking case is France, where snap elections led to a fractured parliament. In this scenario, the left and centre worked together to keep the far-right out of power, resulting in no single party securing a majority; highlighting deep political divisions. 

Meanwhile, there is growing concern about the rise of far-right parties. Notable examples include Reform in the UK, the Freedom Party in Austria, National Rally in France, Chega in Portugal, Alternative for Germany, and Romanian presidential candidate Călin Georgescu. Beyond the ebb and flow of far-right movements in Europe, the key takeaway from last year’s elections is that far-right sentiments are now deeply rooted – changing the face of European politics.

Freedom and fairness in elections have varied by region. Countries like Botswana and Senegal saw peaceful transitions of power, which strengthened their democracies. By contrast, elections in India and South Africa signalled resistance to democratic erosion, but did not mark a complete reversal of previous trends.  

Ultimately, people’s voting patterns underscore a global desire for change, but the electoral outcomes have been far from uniform. Economic anxiety, political polarisation, and shifting ideological currents have reshaped governments worldwide, leaving uncertain prospects for democracy’s future.

The research and methodology behind the Global Parliament Index strive for objectivity and balance. Critiqued through an external informal peer review as well as the consultation of an internal advisory team, the Index comprises expert knowledge from a wide range of political perspectives in its assessment. The precise allocation of governments to each of the categories is a science as well as an art, and on occasion our team of experts have applied judgement where a governing Party has complex or multiple identities. 

The study analyses the political alignment of the national rather than devolved or State governments in each nation around the world.  The category allocated to each governing political party is based on a unique method which considers multiple factors including international and regional political affiliation, political and economic policies, international political engagement and a historical context of the party’s platform. 

Arden’s Global Parliament Index uses recognised world regions established in the SDG framework of the United Nations. Arden’s political spectrum category is provided alongside other indices such as the Freedom House Democracy Index ratings in order to capture a well-rounded snapshot of the state of democracy across each state
