Overall trend: Generally, food takes up the biggest share of the budget, while entertainment accounts for the smallest.
Details: In Norway, the average spending on food is 3,200, which is the highest among the countries surveyed. Transport expenses are highest in Germany at 1,500, whereas the UK spends the least on entertainment, only 400.

- Gunakan verb tenses yang konsisten, biasanya simple present untuk data yang tetap.
- Hindari kata very atau really ; ganti dengan angka atau kata sifat yang lebih tepat.
- Perhatikan satuan (percent, million, thousand) dan pastikan konsistensi.
- Jika ada dua data yang berlawanan, gunakan kata whereas atau while .
- Sertakan kata penghubung (however, moreover, consequently) untuk alur yang lebih logis.
