Forecasting the Population in the City of Medan in 2018: A Statistical Analysis

Introduction

The city of Medan, located in the province of North Sumatra, Indonesia, is one of the largest cities in the country. With a population of over 2 million people, Medan is a hub of economic, cultural, and social activities. However, the rapid growth of the population in Medan has put a strain on the city's infrastructure, services, and resources. Therefore, it is essential to forecast the population of Medan to ensure that the city is prepared to meet the needs of its growing population. This article explores the forecasting of the population in the city of Medan for 2018 using the double exponential smoothing method.

Methodology

The double exponential smoothing method is a forecasting technique that takes an average of the previous period values to estimate the values in the future. This method is particularly useful when the available data has a fluctuating pattern, which is often the case with population data. The data used in this study included the population of Medan from 2006 to 2015. The sample analyzed covered all data on the population of Medan City during that period.

To analyze the data, the Statistical Package for Social Science (SPSS) software was used. The analysis was carried out using multiple linear regression methods to process the data. The results of the smoothing analysis showed that the double exponential method of Brown gave a significant result with the smallest mean square error (MSE) of 754,102,045 with α = 0.5.

Results

The equation of forecasting the number of population that can be expressed as:

ft + m = 2,268,095 + 23,908

From this equation, it is estimated that the population in Medan for the 13th period or in 2018 is 2,279,829 people.

Additional Analysis and Explanation

Dual exponential smoothing is one of the very useful methods in the forecasting field, especially when the available data has a fluctuating pattern. This method allows researchers to be more flexible in capturing changes in population data trends, which can be caused by various factors such as migration, natural growth, and government policy.

The use of data from 2006 to 2015 allows researchers to capture population growth patterns that have occurred over the past decade. Thus, the forecasting produced becomes more accurate because it is based on quite relevant historical data.

Implications for Policy Makers and Urban Planners

The results of this study are very beneficial for policy makers, urban planners, and related institutions in formulating policies oriented towards sustainable population growth. By knowing the prediction of the population in the future, they can be better prepared in planning infrastructure, public services, and social programs needed by the community.

Medan City, as one of the big cities in Indonesia, has a fairly complex population dynamics. Therefore, it is essential for researchers and policy makers to continue to monitor and update the data and forecasting techniques used to be in accordance with the latest developments. Thus, the forecasting produced is not only accurate, but also relevant to the conditions and real needs of the community.

Conclusion

Through a deep understanding of forecasting techniques and appropriate application of data, it is hoped that better planning can be realized for the city of Medan in the future. The forecasting of the population in Medan for 2018 using the double exponential smoothing method has provided valuable insights into the population growth patterns of the city. This study highlights the importance of using accurate and relevant data in forecasting population growth, and the need for policy makers and urban planners to be aware of the latest developments in population dynamics.
