Each year, the world’s population is growing and growing. By 2025, it is estimated that the world population will be around 8.1 billion. Compared with the 7.8 billion people walking on earth right now, it is evident the fast pace at which the population is growing.

Of course, some cities around the world are growing faster than others. To help understand which regions have a higher growth rate, the United Nations analyzed data from all around the globe to understand who were the top 20 fastest growing in the world. By measuring this, the UN could estimate the average annual growth rate of the cities from 2020 to 2025.

Highest Growing Regions

The cities that present a bigger growth rate are located mainly in Africa. 17 out of the 20 cities on the list are in the continent - and 4 are only in Nigeria! The Democratic Republic of Congo and Angola each have 3 cities on the list. This is mostly due to the high birth rate the region has. A 2019 World Bank research showed that the fertility rate in Sub-Saharan Africa was 4.6, while it is 2.4 in the global panorama.Nigeria, in particular, is one of the strongest economies on the continent, since it is mainly based on petroleum. Due to the country’s young population and high birth rate, Nigeria has a rising workforce. As much as it can sound like a blessing, there are also some downsides to it, especially because of rural exodus - which, in turn, creates bigger cities. This, in turn, leads to less farming area, and the country now faces the possibility of having to import basic food staples. All the 3 cities outside of Africa on the list are in Asia - one in Bangladesh, one in China and another Indian city. As much as this can be surprising to most people, even though China is one of the biggest countries in the world, it has a fairly small birth rate. Something that was mainly due to the Chinese one-child policy, which was only recently discontinued. But it is not all fun and games for the fastest growing cities in the world. A big population also means that the places will have to adapt their space in terms of infrastructure. This will also lead to significant changes in the city's mobility and sanitation. If not done correctly, the cities’ growth will most likely lead to pollution, high costs of living, and overcrowding.

City by city

See below the complete list published by the United Nations on the fastest growing cities worldwide.

  1. Gwagwalada - Nigeria - Africa - 6.46% Annual Growth Rate
  2. Kabinda -  Democratic Republic of Congo - Africa - 6.37% Annual Growth Rate

Eyes on Europe

As you can see, all the cities on the list are above the 5% Annual Growth Rate, something that is significantly higher than most cities in Europe. The fastest growing city in Russia, Balashikha, has a growth rate of 2.01%. In accordance with that fact, the growth rate of the top 20 fastest growing cities in Europe range from 0.99% to 2.01% - almost half of the pace happening in Africa. This, coupled with the older population that live in the region, can mean future problems for the countries’ workforce.


Paired with the phenomenon of increasingly bigger cities, here comes another new concept: megacities. As the name suggests, “megacities” are simply cities with much more population than other ones. Usually, this means more than 10 million people living in each one of these cities. Even though the biggest cities of the world will soon be concentrated in Asia and Africa, there are megacities in all other continents of the world, such as São Paulo, in Latin America, and Paris, in France. In fact, Brazil, China, Russia, China, the United States, Japan, and Pakistan are the only countries that currently have multiple megacities.

What does it mean?

Okay. Now you know that Africa and Asia are outpacing growth in other regions. But what does it mean? Basically, this can be a sign of an important economic shift, where the megacities will play a more important role in the world’s economy.That is because, until 2050, it is expected that Sub-Saharan Africa will be home to almost 2 billion people - most of them below the age of 25. As each country will struggle to employ all its population, this number represents a vast labor force not only for the region, but also for other continents. This also represents an opportunity for growth and innovation. Actually, during the pandemic, the African continent has already begun to explore and capitalize digital advances in traditional and new sectors. With such a huge number of people living in the region, Africa is becoming more and more interesting for other countries to make business. For example, China is already investing in infrastructure projects in the region. Other places, such as the NATO countries, are also committed to investing huge amounts on the continent.

Collaborative translation is a powerful tool for your business if you’re looking to expand to new global markets. By coordinating a team of professionals who work together in real-time, you can quickly deliver high quality translations that resonate with local audiences.

But what if you don't know how to synchronize a large team's efforts? Or are you‌ struggling to find the right software for a well-coordinated translation process? Well, look no further! In this guide, you'll learn all the know-how's of collaborative translation to bring your brand to global audiences.

  3. Best practices for collaborative translation and global market success

What is collaborative translation?

Collaborative translation is when multiple people simultaneously work together to translate content. A collaborative translation process often makes use of specialized tools and software to make sure the translation is quick, accurate, and consistent.

  • Example: Let's say you're a B2B SaaS company looking to translate your marketing materials into a new language to connect with potential clients abroad. Use collaborative translation to bring together translators, developers, and other specialists to translate content into many languages at once.

Your team can use a collaborative translation platform like Redokun to work on projects simultaneously. A coordinated workflow will make sure that your translations use the same terminology and style, improving the quality of the translated product for your target audiences.

Collaborative Translation vs. Crowdsourcing

People often confuse collaborative translation with crowdsourcing and think the two are the same. However, these approaches to translation are different.

Crowdsourcing is when a large group of people contributes translations, often through an open call or invitation by a company or author. Brands can turn to crowdsourcing, community translation, or volunteer translation when they are looking to reduce costs and accelerate the process, especially for large multi-language projects.

In crowdsourced translations, the contributors can be volunteer translators, subject matter experts, or just anonymous individuals online. In other words, you may not know who's worked on the translation and what their qualifications are. It makes crowdsourcing distinct from collaborative translation, where the team would be an established group of professionals you've selected

Why seamless translation collaboration is important

As a busy B2B/B2C marketing manager or project manager, you might ask yourself: Isn't the "divide and conquer" a better strategy when working on a translation or localization project? It seems logical that each project team member, including translators, designers, and editors, works on their tasks separately and step by step.

However, collaborative translation can help your team reap many benefits compared to a traditional approach to translation projects:

Reasons why seamless translation collaboration is important
  • Produce high-quality translations consistently. When your whole team works on a translation project simultaneously on one platform, it's easier to stay in context and keep track of the translation accuracy for every target language. On top of that, your team can conduct agile QA throughout the project cycle.
  • Faster turnaround times. By working together, your team can complete projects faster and more efficiently. Centralization saves a lot of time at every stage of translation. And since your team can work on more than one translation at a time, you can publish your translated content in several new markets at once.
  • Reduced costs. You get to improve efficiency while working with a smaller team of translators. The smaller and more coordinated the team, the less the risk of costly translation errors. It means reduced translation costs and better project budget compliance.
  • Increased flexibility. Collaborative translation allows your team to produce translations into many languages at once and easily make changes to any project document. You can conveniently engage in a feedback loop and guarantee a continuous localization process.
  • Better communication. Collaborative translation effectively brings all members of your localization team together on one platform. It helps you make sure that everyone is working toward the same goals ‌and simplifies overall localization management.

Six best practices for collaborative translation and global market success

To be great at collaborative translation, you need to approach it strategically. Even if you've never used this approach before, you can follow the six steps below to build an efficient collaborative translation workflow. And if you're already familiar with this method, these practices will help you improve the way you collaborate on any translation projects.

Six best practices for collaborative translation for your global business success

1. Work out a detailed project plan

Before you start working on translations together, you need a clear-cut project plan. You should first identify the following items.

  • Project timeline: Define crucial deadlines, project milestones, and the overall project duration.
  • Translation volume and key deliverables: Calculate the general word count, and determine the workload for every language pair if you translate into multiple languages.
  • Project budget: Keep in mind possible added and hidden translation costs.
  • Project team: Define what kind of specialists you need: translators, editors, proofreaders, etc. Will you need to find external translators? Consider all your HR needs in advance.
  • Your approach to the translation process: How much do you want to rely on machine translation? At what point will you edit translated strings? Answer all these questions before you go on.
  • Quality assurance protocol: Establish an efficient QA procedure for all the language pairs you're working on.

It may sound like a handful but the more detailed the plan, the more streamlined the translations will be down the road. Besides, you can already use Redokun to boost this stage of the localization process!

Redokun is a translation management system you can use to automate, coordinate, and optimize your translation processes from content creation to publication.

Redokun simplifies your project planning. In particular, you can use the tool to:

  • Monitor your ongoing translations easily. Keep track of all of your translation files and projects across multiple languages in one space, and check their progress at a glance.

  • Meet deadlines with digest emails. Redokun will send you daily or weekly email digests to update you on the progress of translations. From there, you can initiate one-click reminders to your translators who are potentially falling behind schedule.
  • Making budget planning easier. Redokun has a transparent, scalable pricing structure that will cover exactly the volume of work your project needs.
Redokun is an easy-to-use tool that requires no onboarding. Your team can start using all the system’s features right away. During your project planning stage, you won’t need to factor in a lengthy training period to introduce team members to the tool.

2. Divide tasks and assign responsibilities the smart way

Good collaboration is impossible without a well-planned distribution and organization of roles and tasks. Ensure that every team member is on the same page and understands their respective responsibilities.

For example, the project managers should divide ‌translation tasks among translation team members according to their language proficiency, area of expertise, or subject matter knowledge.
  • On Redokun, you can invite translators to work on different language pairs and content types depending on their skills. All you need to do is enter the translator's email. The software will send them an email invitation and let you know once they've started translating the file.
  • You can also invite several translators to work on one document.
How to invite translators to Redokun

To maximize the efficiency of project management and task division, establish a clear structure of your workflow. Make sure all your pages, files, and folders are well organized and team members know where to find necessary resources for their respective tasks. A centralized, cloud-based storage for all your documents is a must.

  • Redokun is a cloud-based software that makes file management easy. You can create folders and customize permission settings for multiple users for better organization. No more need to look for spreadsheets and lost documents scattered around different digital locations.
  • Don't forget to make the most of the Reporting Dashboard. It shows you the status of the translation project and helps you see how users distribute tasks (for example, what methods they use to translate different content segments).

3. Enhance the collaborative translation process with clear communication

It's important to have open communication channels among all team members in your translation project, including internal and external translators. For a successful collaboration effort, you need a shared communication space to:

  • Conduct regular check-ins.
  • Discuss translation options and other aspects of the working process.
  • Update and adjust requirements and guidelines.
  • Maintain feedback loops.
It's up to you to choose between email, messengers, or tools like Google Drive or Slack to keep your collboarative operations flowing. However, using multiple channels for different aspects of the project can get messy. It's harder to manage your team and make sure all collaborators are up to date on the ongoing translation tasks.

You can avoid these potential problems by centralizing all your communications and project management. With translation software like Redokun, you can manage, translate, communicate, and collaborate — all in one place.

  • Translate content in context. Your translators or editors can use page previews in Web Editor to understand the context of the text while working on it.
  • Work together in real-time. Use Redokun as a full-scale collaborative translation platform. It enables real-time cooperation among your team members, improving efficiency and reducing communication errors.
  • Use comments, mentions, and notifications to exchange feedback quickly. Redokun's Web Editor is a convenient place to stay in touch and discuss your translation progress every step of the way.

  • Create a hybrid workflow. Work with your in-house teams or external translators to suit different localization project formats and scalability needs.

4. Use machine translation and translation memory tools

Computer-assisted translation tools are a great addition to human translation. Machine translation (MT) helps your collaborators speed up the localization process by automating translation. Of course, it doesn't have the quality of a human professional translation — it’s more like a helping hand that's always there to facilitate the translation of complex phrases or new terms.

  • Redokun is integrated with two Machine Translation tools: Google Translate and DeepL. Translation suggestions by these two tools pop up right below where the translator should key in the translation, as shown here.

To enhance collaboration even further, consider using translation memory tools. They ensure consistency and save translation software users a lot of time.

Translation memory (TM) is a translation technology that stores previously translated sentences or phrases as segments and creates a unique database for your localization projects. You can reuse your translation to increase efficiency and consistency in ongoing and future translations.

With Redokun as your collaborative translation platform, you can leverage TM to:

  • Consistently translate any repeated word, phrase, or sentence across different language pairs and documents. It's especially important for translating technical terms, marketing slogans, CTAs, and other catchphrases. Translation memory helps you stay consistent in your marketing messaging.
  • Pre-translate your entire documents. Combine TM matches from your previous translations with Machine Translation to get a fully pre-translated document even before your team gets to work.
  • Manage your translation memory database. Import and customize your TM database to further improve translation quality and consistency.
”The speed of translation is quite impressive in that it doesn’t take [much time], maybe a couple of minutes when you translate from English to eight markets. I think that’s what I’m most impressed by.”

5. Use glossaries and style guides

Glossaries and style guides are valuable resources your team can use for reliable reference.

A glossary is a list of terms and their corresponding translations that are specific to a company or industry.

A style guide outlines the preferred tone, voice, and style for a company's marketing materials across markets and languages.

Your collaborators can refer to these resources when they’re not sure about a translation. For example is when they're deciding how to translate a company abbreviation, whether to the Oxford comma, or choosing the right tone to address customers, etc. No more ambiguity about linguistic, stylistic, and cultural aspects of your translations.

  • Use Redokun's glossary feature to create a glossary and style guide that outlines rules for spelling, grammar, punctuation, terminology, and tone specific to your project.

6. Continuously review and revise

A key benefit of a collaborative translation platform is the ability to review and revise translations in an agile and efficient manner. By involving multiple specialists in the process of editing and QA, you can guarantee accuracy and consistency in the translated content at every stage of the project.

To implement effective review and revision procedures in your collaborative translation projects, it is important to:

  • Plan for review and revision in advance. Identify who will be responsible, set the timeline, and use specific tools.
  • Consider involving in-country reviewers who are familiar with the local market and culture to ensure that the translations are accurate and appropriate for the target audience.
  • Perform regular QA checks. They should include consistency in terminology and formatting, and verify that the translations are free from grammatical errors and typos.
Pro-tip: Ever experienced the headache of having to update a translation that’s already 70% done when there is a last-minute change to the source document?

With Redokun’s revision feature, you don’t have to spend hours poring over Excel sheets and comparing files to spot the places where new words have been added or sentences have been changed. Just upload the latest document version and the system will identify new text that needs translating — saving your team’s time and effort while keeping previous translations intact.


Collaborative translation is an excellent approach if you want to improve the consistency of your translations, reduce costs, and establish a strong presence in global markets.

The key to seamless collaboration is a combination of careful planning, role distribution, agile QA, and smart use of translation software.
