Market demand and its fluctuations. Total market demand can change due to changes in consumer purchasing power, tastes and preferences, expectations of future needs, and rising or falling prices and incomes. Furthermore, market contraction and expansion can be linked to changes in the social structure of the population, the prevalence of a particular age group, consumer behavior patterns and values, the emergence of substitute products, etc.
Seasonal and economic fluctuations. The market papua new guinea cell phone database capacity for seasonal goods fluctuates throughout the year. Periods of increased demand and decreased consumer interest in products can be affected by weather conditions, seasonal changes, and holidays. Constantly changing consumption trends must be taken into account when assessing capacity; otherwise, the indicator will be inaccurate. Potential market size also depends on economic activity, which is characterized by periods of recession and recovery. Economic fluctuations influence changes in employment, inflation, solvency, and creditworthiness of the population.
The Impact of Competition on Market Capacity. Market capacity can be larger or smaller depending on the quality characteristics and price of a product, as these parameters largely determine whether consumers will be willing to purchase the product or prefer a similar product from a competitor .
The Role of Technology and Innovation in Changing Market Capacity. New technologies have a dual impact on market capacity. On the one hand, they can fundamentally impact market structure, completely altering demand, devaluing previous experience and investments, and creating new consumer needs. On the other hand, the use of innovations in production allows companies to reduce production costs and sell them at lower prices, which contributes to an increase in volume but, in some cases, can reduce it in monetary terms. For example, technological advances have lowered laptop prices, while also facilitating the emergence of a tablet market, which has attracted some consumers who previously used laptops.
Methods for assessing market volume and capacity
All methods for assessing market capacity and volume can be divided into qualitative and quantitative:

Qualitative methods. These involve the analysis of primary data—information collected by the company specifically to calculate the necessary metrics. Qualitative methods include competitor analysis, surveys, and expert assessments. Not all companies use primary data in practice due to the significant costs of conducting research, the broad geographic scope, or the difficulty of finding experts capable of providing valid assessments.
Quantitative methods. These methods rely on secondary data: production and sales statistics, market dynamics, and forecasts. They are published by industry agencies, specialized organizations conducting consumer research, industry and specialized journals and online publications, professional associations, and the companies themselves as part of standard reporting.
