Okay, I need to create a Wikipedia-style document about "인구통계적 분할" (Demographic Segmentation) under the categories of Economics, Market and Business, Marketing Strategy. Let me start by understanding what demographic segmentation is. It's a method of dividing a market into groups based on demographics like age, gender, income, etc.

First, I'll structure the document with an H1 title. Then an overview section explaining what it is. Next, sections for different aspects: definition and importance, key factors (age, gender, income, education, occupation), applications in marketing, advantages and challenges, and maybe a conclusion. Also need to include references or related documents.

I should make sure the content is accurate and objective. Use examples where possible. For each section, explain terms if needed. Like when I mention "income level," I might need to define it briefly. Keep the language clear and easy to understand. Avoid jargon unless necessary, but since it's a professional document, some terms are okay with explanations.

Check for depth: cover different demographic factors, how they're used in marketing strategies, benefits, and potential issues like over-segmentation. Maybe include examples of companies using this strategy. Also, think about the structure of each section. Use H2 for main sections and H3 for sub-sections if needed.

Need to ensure it's at least 800 characters. Let me count: the example response is around 1500 words, so that should be fine. Make sure to use markdown formatting with proper headings, lists, maybe a table for key factors. Avoid any markdown in the thinking process but structure the final answer correctly.

Also, check if there are any common mistakes. For instance, not differentiating between demographic and psychographic segmentation. Need to clarify that demographic is based on statistical data, while psychographic is more about lifestyle. But since the topic is specifically demographic, focus only on that.

Include real-world examples like how a company might target young adults vs. seniors. Mention tools or methods used in demographic analysis, like surveys or data analytics. Maybe touch on challenges like changing demographics over time and the need for continuous research.

Make sure each section flows logically. Start with an introduction, then break down into key factors, applications, pros/cons, and conclude with its importance in marketing strategy. Add references to academic sources or industry reports if possible, but since it's a wiki-style document, maybe just mention them as related documents without citations.

Check for clarity: avoid overly technical language unless explained. Use bullet points for the key factors under each section. Maybe use a table to summarize the different demographic variables and their applications. Ensure that all parts are covered thoroughly but concisely.
