The database population.xlsx contains data on the populations of the 150 states from 1990 to 1999. For each of the following requirements, create a separate worksheet and extract the data from the original database.
a. Sort the states by population in 1999, from highest to lowest.
b. Were the 10 states with the highest population the same in 1999 as in 1990?
c. Which state had the largest percentage increase in population from 1990 to 1999?
d. Which states had a population of more than 2 million or less than 1 million in 1995?

The analysis of population data across different states over a decade offers valuable insights into demographic changes, migration patterns, and population growth trends. In this study, data from the Excel file "Population.xlsx," which details the population figures of 150 states from 1990 to 1999, is utilized to fulfill several specific analytical objectives. These include sorting states by population in 1999, comparing the top populous states between 1990 and 1999, identifying the state with the most significant percentage growth, and filtering states based on specific population thresholds in 1995.
Sorting States by Population in 1999:
The first task involves sorting all states according to their population in 1999, from the highest to the lowest. Using Excel, this is achieved by selecting the relevant data column for 1999 population, applying the "Sort Largest to Smallest" function. This sorted list helps identify the most and least populous states as the decade concludes, offering a snapshot of demographic powerhouses and less populated regions. This ranking not only aids policymakers and planners in resource allocation but also provides a foundation for further analysis of population shifts and regional development.
Comparison of the Top 10 Most Populous States in 1990 and 1999:
The next step assesses whether the same 10 states with the highest populations in 1990 remained dominant in 1999. This involves extracting the top 10 states for each year and comparing the lists. If the same states occupy these top ten positions, it indicates relative demographic stability; deviations suggest significant shifts possibly driven by migration, economic changes, or policy impacts. This comparison is visualized through side-by-side lists or a table highlighting changes, offering insights into regional growth dynamics.
Identifying the State with the Largest Percentage Population Increase:
Calculating the percentage increase for each state from 1990 to 1999 involves:
\[ \text{Percentage Increase} = \left( \frac{\text{Population in 1999} - \text{Population in 1990}}{\text{Population in 1990}} \right) \times 100 \]
Applying this formula in Excel, each state's percentage growth is calculated and then filtered or sorted to identify the maximum value. The state with the highest percentage increase signifies regions with rapid growth, potentially due to economic opportunities, urbanization, or other socio-economic factors. These insights can guide investments and infrastructure development.
Filtering States with Populations >2 Million or
Finally, filtering states based on their population sizes in 1995 helps identify regions experiencing significant demographic shifts. Using Excel's filter functionality, states with populations exceeding 2 million are listed separately from those with populations below 1 million. Analyzing these categories reveals patterns of growth or decline, urbanization, and rural depopulation, informing targeted policy measures.
In summary, leveraging Excel's data manipulation features such as sorting, filtering, and formula calculations enables comprehensive analysis of decade-long population trends across states. These insights are essential for policymakers, urban planners, and researchers focusing on demographic dynamics, regional development, and resource allocation strategies.
