Sales analysis

Interactive dashboard




Here are some key findings from my analysis of sales data across multiple countries:


  • Sales Growth: Mexico has the highest sales growth at 145%.
  • Profitability: France has the highest cross-profit at $54 million. This is likely due to French customers being more willing
    to buy at full price compared to the US, where discounts heavily influence purchasing decisions.
  • Non-discounted Sales: When no discounts are offered, France exhibits the strongest non-discounted sales at $5 million, followed by Canada at $4 million and Germany at $5 million. The US and Mexico have similar non-discounted sales figures of around 1million each

Customer behavior

Interactive dashboard








Here are some key findings from my analysis of sales data across multiple countries:


  • Global Trend: Customers with children contribute the majority of revenue across all countries analyzed (71%). Customers without children contribute the remaining 29%.
  • US Breakdown:
    • Children: Customers with children contribute a higher percentage of revenue (79%) compared to the global average.
    • Age Group: The 30-60 age group generates the most revenue (75%) within the US.
  • UK Breakdown:
    • Children: Customers without children contribute a slightly higher percentage (28%) compared to the global average.
    • Age Group: Similar to the US, the 30-60 age group generates the majority of revenue (73%) within the UK.
  • Australia Breakdown: (Surprisingly)
    • Children: Customers without children contribute a significantly higher percentage (42%) compared to both the global average and other countries.
    • Age Group : The 30-60 age group again generates the most revenue (77%) within Australia.

    • This analysis highlights the dominance of the 30-60 age group across all countries in terms of revenue generation. However, the influence of parental status on purchasing behavior varies by region. Further investigation might be needed to understand the buying habits of customers without children in Australia.
