- database
- Maintained by Federal Reserve Bank of St. Louis provides comprehensive collection of economic and financial data
- Collects data from government agencies (Bureau of Labor Statistics) and private sources ( ) covering wide range of variables
- Offers time series data on key economic indicators such as GDP, inflation (CPI), , and interest rates ()
- Accessing and using FRED data
- Access data through FRED website or API for flexibility in data retrieval
- Search for specific data series, view interactive charts, and download data in various formats (CSV, Excel) for further analysis
- Utilize data for economic research, trend analysis, and data-driven decision-making in finance and policy
- Consider (e.g., daily, monthly, quarterly) when selecting and analyzing time series
Calculation of percentage changes
- Calculating percentage changes
- formula:
- Measures relative change in variable over specified time period to normalize comparisons
- Positive percentage change signifies growth (10% increase in GDP), while negative change indicates decline (-2% decrease in sales)
- Interpreting percentage changes
- Provides insight into magnitude and direction of changes in economic variables for meaningful analysis
- Enables comparison of changes across different time horizons (month-over-month vs year-over-year) or between variables (GDP growth vs employment growth)
- Identifies trends (consistent positive changes), patterns (seasonal fluctuations), and turning points (shift from positive to negative changes) in data
- Limitations of percentage changes
- Sensitive to choice of base period, as different starting points can yield different percentage changes
- Does not capture absolute level of variable, as focus is on relative change (10% growth from 1,000)
- Outliers or one-time events can distort percentage changes, requiring careful interpretation
Presentation methods for economic data
- Levels
- Represent actual value or quantity of economic variable at specific point in time
- Useful for understanding current state and absolute size of variable
- Examples include nominal GDP ($21 trillion), unemployment rate (5.5%), and stock market index level (S&P 500 at 4,000 points)
- Percentage changes
- Measure relative change in variable over time, typically expressed as growth rates
- Useful for comparing pace of change across different periods or variables
- Examples include annual GDP growth rate (2.5%), monthly inflation rate (0.3%), and year-over-year change in retail sales (8%)
- Indexes
- Measure change in variable relative to base period, typically set to 100 for easy interpretation
- Useful for tracking overall trend and long-term movement of variable
- Examples include for inflation, for real estate market, and (PMI) for manufacturing activity
- Choosing appropriate presentation method
- Depends on analysis purpose and data characteristics for effective communication
- Levels provide snapshot of current economic conditions and sizes of variables
- Percentage changes facilitate growth rate comparisons and trend identification
- Indexes enable long-term tracking and cross-variable or cross-region comparisons
Advanced Data Analysis Techniques
- adjustment
- Removes regular seasonal fluctuations from data to reveal underlying trends
- Important for accurate interpretation of economic indicators affected by seasonal patterns
-
- Determines whether observed relationships or changes in data are likely to be real or due to chance
- Crucial for drawing reliable conclusions from economic data analysis
- and
- Measures strength and direction of relationships between economic variables
- Helps in forecasting and understanding causal relationships in economic systems
Data Quality Considerations
-
- Economic data often undergoes revisions as more information becomes available
- Analysts must be aware of potential changes in historical data and their impact on analysis
