Verified step by step guidance1
Understand the concept of exponential growth: Exponential growth occurs when the growth rate of a population is proportional to its current size, leading to faster and faster increases as the population grows.
Consider historical data: Examine population data over the past century to identify trends. Look for patterns that indicate whether the growth has been steady, constant, linear, or exponential.
Compare growth types: Linear growth implies a constant increase over time, while exponential growth implies an accelerating increase. Constant growth means no change in population size, and steady decrease means a consistent reduction.
Analyze the impact of factors: Consider factors such as technological advancements, healthcare improvements, and agricultural developments that have influenced human population growth.
Evaluate the statement: Based on the understanding of growth types and historical data, determine which statement accurately describes human population growth over the past century.
