The table below presents the total national expenditures for health care in the United States, spanning from 2002 to 2024. This data encompasses expenditures for medical research and medical facilities, providing a comprehensive overview of the country's health care spending over the past two decades. In this article, we will delve into the mathematical analysis of this data, exploring trends, patterns, and projections to gain a deeper understanding of the nation's health care expenditures.

Table: National Health Care Expenditures (2002-2024)

Year	Expenditures (Billions of Dollars)
2002	1.3
2003	1.4
2004	1.5
2005	1.6
2006	1.7
2007	1.8
2008	1.9
2009	2.0
2010	2.1
2011	2.2
2012	2.3
2013	2.4
2014	2.5
2015	2.6
2016	2.7
2017	2.8
2018	2.9
2019	3.0
2020	3.1

2023	3.4
2024	3.5

Upon examining the table, we notice a steady increase in national health care expenditures over the years. This trend can be attributed to various factors, including an aging population, advancements in medical technology, and an increase in healthcare services. To quantify this trend, we can calculate the average annual growth rate (AAGR) of the expenditures.

Calculating Average Annual Growth Rate (AAGR)

AAGR can be calculated using the formula:

AAGR = (End Value - Beginning Value) / Number of Years

Using the data from 2002 to 2024, we can calculate the AAGR as follows:

AAGR = (3.5 - 1.3) / 22 AAGR ≈ 0.12 or 12%

This indicates that the national health care expenditures have been growing at an average annual rate of 12% over the past two decades.

To further analyze the trend, we can perform a linear regression analysis on the data. This will help us identify the relationship between the year and the expenditures.

Linear Regression Model

The linear regression model can be represented as:

Expenditures = β0 + β1 * Year + ε

where β0 is the intercept, β1 is the slope, and ε is the error term.

Using the data from 2002 to 2024, we can estimate the parameters of the linear regression model as follows:

β0 ≈ 0.83 β1 ≈ 0.12

The linear regression model can be represented as:

Expenditures ≈ 0.83 + 0.12 * Year

Projection of National Health Care Expenditures

Using the linear regression model, we can project the national health care expenditures for the year 2024 as follows:

Expenditures ≈ 0.83 + 0.12 * 2024 Expenditures ≈ 3.5

This projection is consistent with the data presented in the table.

In conclusion, the national health care expenditures have been growing steadily over the past two decades, with an average annual growth rate of 12%. The linear regression model provides a good fit to the data, allowing us to project the expenditures for the year 2024. This analysis highlights the importance of understanding the trends and patterns in national health care expenditures, which can inform policy decisions and resource allocation.

Based on the analysis, we recommend the following:

Continued monitoring of national health care expenditures: Regular monitoring of the expenditures will help identify any deviations from the trend and inform policy decisions.
Investment in medical research and facilities: Continued investment in medical research and facilities will help drive innovation and improve healthcare outcomes.
Efficient allocation of resources: Efficient allocation of resources will help ensure that the increasing expenditures are used effectively to improve healthcare outcomes.

By following these recommendations, we can work towards a more sustainable and effective healthcare system.
