kvartalikasv

Kvartalikasv is an Estonian term meaning quarterly growth, referring to the rate at which a variable increases from one quarter to the next. It is commonly used in economics and business to describe short-term performance.

Calculation is straightforward: the quarterly growth rate is ((Value in quarter t) − (Value in quarter t−1)) / (Value in quarter t−1) × 100. If data are seasonally adjusted, the growth reflects underlying trends after removing seasonal patterns. If not adjusted, the figures can be more affected by regular seasonal swings.

Interpretation: a positive kvartalikasv indicates expansion, while a negative value signals contraction. The magnitude conveys the pace of change, but quarterly data can be volatile and subject to revisions, especially in early releases or for smaller economies.

Real vs nominal: kvartalikasv can be reported in real terms (inflation-adjusted) or nominal terms (current prices). Real kvartalikasv measures volume changes rather than price changes and is often preferred for comparing true growth over time.

Relation to annual growth: quarterly growth rates can be compounded to estimate annual growth, or compared on a year-over-year basis by examining the same quarter in different years. Both approaches help assess longer-term trends beyond single-quarter fluctuations.

Data sources: kvartalikasv figures are produced by official statistics agencies and international organizations, including national statistical offices and bodies such as the OECD or IMF. Revisions are common as more complete data become available.

Limitations and considerations: base effects, seasonal patterns, data revisions, and measurement methods can influence kvartalikasv. Users should consider whether the data are seasonally adjusted, real or nominal, and the reporting frequency when interpreting the figures.
