# Projection vs. Prediction: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on November 9, 2023
Projection is an estimate based on current data or trends, while prediction is a statement about the future, often based on judgment or speculation.

## Key Differences

Projection often involves extending current data into the future based on an existing trend or patterns. It is used in various fields like finance, population studies, and meteorology to estimate future outcomes based on systematic analysis. Projections are not definitive forecasts but rather scenarios that could occur if current trends continue without significant change.
Prediction involves forecasting what will happen in the future and can be based on intuition, guesswork, scientific methods, or historical data. Unlike projections, which are usually model-based extrapolations, predictions often involve a degree of uncertainty and are more speculative. They are commonly used in contexts like weather forecasting, sports betting, and economic forecasting.
A projection is typically more methodical and may involve mathematical or statistical models. For example, a demographer might project population growth based on birth and death rates. This method relies on quantifiable data and often assumes that the current conditions will not change dramatically in the future.
In contrast, a prediction is more of a general statement about future events and can be based on a wider range of information, including patterns, expert knowledge, or even subjective opinions. For example, an economist might predict a recession based on current market trends, policy changes, and economic indicators, knowing that unforeseen events could influence the outcome.
While both terms deal with the future, projections are generally more data-driven and are often presented with a range of possible outcomes, each associated with a certain set of assumptions. Predictions, on the other hand, are more definitive but also more uncertain, as they assert one specific outcome that the predictor believes is likely to happen.

## FAQs

#### Can predictions be accurate?

Predictions can be accurate, but they are not guaranteed to be correct as they often involve elements of uncertainty.

#### What is a projection in business?

In business, a projection is an estimate of future sales, profits, or other financial metrics based on current trends.

#### Are projections always numerical?

Projections are often numerical but can also involve qualitative scenarios based on quantitative data.

#### How do scientists use projections?

Scientists use projections to estimate future occurrences based on current models and understanding, such as climate change projections.

#### Do projections take into account new trends?

Projections may take new trends into account if they are consistent and there is sufficient data to include them in the analysis.

#### Do predictions always come true?

No, predictions do not always come true; they are best guesses about future events.

#### What is the purpose of making a projection?

The purpose of making a projection is to plan for future scenarios by analyzing current trends and data.

#### Can a prediction be a hypothesis?

Yes, a prediction can be a hypothesis, especially when it is to be tested in an experimental setting.

#### Can projections be biased?

#### How often are projections updated?

Projections are updated as new data becomes available or when underlying assumptions change.

#### Can prediction be used in planning?

Prediction can be used in planning, particularly when there is confidence in the predictive model or past accuracy.
