Career Mobility of Planning Alumni in the United States: Evidence from Professional Profile Data using Large Language Models
This study analyzes over 130,000 US planning alumni using large language models to extract LinkedIn data, revealing that boundaryless career patterns, strategic lateral moves, geographic mobility, and strong professional networks are key drivers of upward career mobility, while technical skills and AI proficiency play more limited roles in senior advancement.

Imagine the career of a city planner not as a straight ladder you climb rung by rung, but as a hiking trail through a vast, changing landscape. Some hikers stick to one well-marked path, while others jump between trails, cross different terrains, and even explore new countries.
This study, by Wang and Jo, is like a massive map drawn from the digital footprints of 130,000 city planners in the United States. The researchers used advanced AI (specifically Large Language Models) to read millions of LinkedIn profiles, turning messy, unstructured career stories into clear data. They wanted to answer: What makes a planner's career "move up" faster and higher?
Here is what they found, broken down into simple concepts:
1. The "Jack-of-All-Trades" vs. The "Specialist"
The Finding: Planners who only stay in one type of job (like only working for the government) tend to move up slower. Those who have worked in multiple sectors (government, private companies, and non-profits) or who have switched industries frequently tend to rise faster.
The Analogy: Think of a career like a toolbox. If you only have a hammer, you can only build houses. But if you have a hammer, a saw, a wrench, and a paintbrush, you can fix anything. The study found that planners who built a "multi-tool" career by working in different worlds (public and private) were more likely to get promoted. It's like having a passport that lets you travel between different "countries" of work; the more countries you visit, the more valuable you become.
2. The "Geographic Passport"
The Finding: Moving around helps. Planners who moved to different states or cities, especially to large, diverse metropolitan areas, advanced more quickly.
The Analogy: Imagine a video game. Playing in a small, empty town (a rural area) limits the number of quests you can take. But playing in a massive, bustling city with thousands of other players (a large metro area) opens up hundreds of new quests, side missions, and opportunities to team up. The study suggests that being in a big, diverse city acts like a "speed boost" for your career, giving you more chances to level up.
3. The "Social Web"
The Finding: The more people you know professionally, the faster you climb. Having a large network of connections and being involved in many different organizations is a huge advantage.
The Analogy: Think of your career as a fishing expedition. If you only have one fishing line (one connection), you might catch a fish once in a while. But if you cast out a giant net with thousands of lines (a large network), you are almost guaranteed to catch something new. The study shows that every extra person you know acts like another line in your net, increasing your chances of catching a promotion.
4. The "Skill Switch" (Hard vs. Soft Skills)
The Finding:
- Early Career: You need technical skills (like knowing software, maps, or data) just to get your foot in the door. It's the "ticket" to enter the game.
- Later Career: As you get senior, soft skills (like leadership, communication, and managing people) become the most important factor for moving up.
- AI Skills: Interestingly, knowing Artificial Intelligence (AI) is now so common that it's just the "baseline." Having AI skills doesn't give you a special boost anymore; it's just expected, like knowing how to use a computer.
The Analogy: - Technical skills are like the engine of a car. You need a working engine to start driving.
- Soft skills are like the steering wheel and navigation. Once the car is moving, the driver's ability to navigate complex traffic and lead the passengers determines how fast and far they go.
- AI skills are like air conditioning. It used to be a luxury feature that made you stand out, but now almost every car has it, so it doesn't make your car faster than the others.
5. The "Boundaryless" Journey
The Finding: The study challenges the old idea that you should stay at one company for 30 years. They found that "boundaryless" careers—where people jump between jobs, switch industries, and take lateral moves (sideways steps)—actually lead to faster upward mobility in the long run.
The Analogy: Think of a climber scaling a mountain.
- The traditional climber stays on one narrow path, going straight up.
- The boundaryless climber might slide down a little to find a better route, jump to a different ridge, or climb a neighboring peak to get a better view.
The study found that the "boundaryless" climber often reaches the summit faster because they are gathering more experience and finding better routes along the way.
Summary for the Everyday Person
If you are a city planner (or anyone in a similar field), this study suggests that staying in one place doing one thing is the slowest way to grow.
To get ahead:
- Travel: Don't be afraid to move to new cities or switch between government and private jobs.
- Network: Make friends everywhere; your connections are your safety net and your ladder.
- Learn: Start with hard technical skills, but quickly pivot to learning how to lead and communicate.
- Embrace Change: Don't fear a "sideways" job move; it might actually be a shortcut to the top.
The researchers used AI to read 130,000 profiles to prove that in the modern world, the most successful planners are the ones who are adaptable, well-connected, and willing to explore.
