Task: 
You are given a table containing structured data and a natural language question referring to the table. Your goal is to analyze the table and provide an accurate and concise answer based on the given data.

Instructions:
1. Understand the Table: Examine the structure, headers, and data in the table. Identify relevant columns and rows related to the question.
2. Interpret the Question: Determine whether the question requires direct retrieval, aggregation, comparison, sorting, filtering, or inference.
3. Extract the Answer: Use logical reasoning and numerical operations (if necessary) to derive the correct response from the table.
4. Format the Answer: No explanation, return the answer in a structured JSON format: {"answer": <answer>}. If the question cannot be answered due to missing or ambiguous data, return a JSON response with {"answer": null}.

Question:
at the end of 2016 , what was the average number of berths per ship in the global cruise fleet?


pre_text: rates are still low and that a significant portion of cruise guests carried are first-time cruisers .
we believe this presents an opportunity for long-term growth and a potential for increased profitability .
the following table details industry market penetration rates for north america , europe and asia/pacific computed based on the number of annual cruise guests as a percentage of the total population : year north america ( 1 ) ( 2 ) europe ( 1 ) ( 3 ) asia/pacific ( 1 ) ( 4 ) .
post_text: ( 1 ) source : our estimates are based on a combination of data obtained from publicly available sources including the international monetary fund , united nations , department of economic and social affairs , cruise lines international association ( "clia" ) and g.p .
wild .
( 2 ) our estimates include the united states and canada .
( 3 ) our estimates include european countries relevant to the industry ( e.g. , nordics , germany , france , italy , spain and the united kingdom ) .
( 4 ) our estimates include the southeast asia ( e.g. , singapore , thailand and the philippines ) , east asia ( e.g. , china and japan ) , south asia ( e.g .
india and pakistan ) and oceanian ( e.g. , australia and fiji islands ) regions .
we estimate that the global cruise fleet was served by approximately 503000 berths on approximately 298 ships at the end of 2016 .
there are approximately 60 ships with an estimated 173000 berths that are expected to be placed in service in the global cruise market between 2017 and 2021 , although it is also possible that additional ships could be ordered or taken out of service during these periods .
we estimate that the global cruise industry carried 24.0 million cruise guests in 2016 compared to 23.0 million cruise guests carried in 2015 and 22.0 million cruise guests carried in .
