# 2024 Week 25 | Sigma: Can you compare these populations?

## Introduction

Welcome to Week Twenty-Five! This week, you’re going to compare US Census data from 2000 and 2010.  In this challenge, we’ll highlight a couple of new formatting additions to Sigma, as well as create a dynamic parameter.

Good Luck!

## Requirements

• On a hidden Data Tab:
• Add the US Census Data:  Sigma Sample Database / FUN / CENSUS / CENSUS
• Note the pre-defined Metrics available.  We will use Population Change and Population Change %
• Group this data table by State
• Find the Population Change by State, using the pre-defined Metric.
• On a visible page:
• Create a Map – Region visualization to visualize the Population Change Percent by State
• Region = State
• Color = Population Change %
• Label = Population Change %
• ToolTip = Population Change
• Show a Title with a descriptive name
• Change the Color Palette
• Create a Slider Input Page Control to input the [Param-Change] and select a value.
• Allow Values 1-10
• Make it Required
• Show Background
• Create a horizontal, stacked bar chart to visualize the States with the Most AND Least Population Change
• Y-Axis = State
• X-Axis
• (Visible Field) Population Change
• (Hidden Field) Create a Boolean Column that determines if the state is in the range of the most or least change, based on the [Param-Change] input.
• Hint:  Use 2 RankDense functions combined with an OR statement.
• Filter the visualization on this column = True
• Formatting:
• Sort by Population Change
• Color:  Population Change %
• Change the Color Palette to match the Map
• Format the X-Axis and Data Labels in SI Units
• Format Population Change in the ToolTip as a Whole Number (full value)
• Standard Deviation of Population Change
• Add a label with value and text in the Bottom Right
• Give the chart a Descriptive Title that includes dynamic text showing the [Param-Change] input value.
• Show the Legend & Header
• Shorten the Field name, to not take up so much space
• Finishing Touches
• Give the Dashboard a Descriptive Title
• Arrange your elements into a cohesive dashboard
